Teaching Statement

Teaching Statement

Vision: Students today have access to a myriad of tools to enhance their learning experience. Effective teachers today must make use of these resources to help their students identify helpful, useful teaching materials and application tools to improve their academic and professional formation. At both undergraduate and graduate level, our role as lecturers, facilitators, and advisors must adapt to find a balance between traditional, proven teaching techniques and new strategies for the current and future generations. From chalk on a board to virtual demos, from hands-on laboratory experiences to remote visualization, from back-of-the-envelope calculations to quick simulations in real time, I focus on the students’ goals. The question “What will they be able to do at the end of this course that they couldn’t do otherwise?” has guided my vision through my courses at UIUC, my mentoring of undergraduate researchers, advising MS and PhD students, developing short courses for multidisciplinary audiences, and creating outreach opportunities for K-12 youth.

Teaching goals: I aim for 5-Cs in our CEE curriculum: Continuity, Creativity, Critical Thinking, Cross-pollination, and CV-building. Continuity: Courses can’t be seen as isolated blocks. There must be an explicit connection between material seen in previous courses with topics that will come later on their program. For instance, practical applications should be discussed from early introductory courses (i.e., “this is how you will use it”), and fundamentals of linear algebra and calculus should be highlighted in advanced courses (i.e., “this is how you finally use it”). Tools and skillsets developed in earlier courses should be utilized later in their degree. If students will spend a year learning a programming language, they should have opportunities to use it in more advanced courses. Creativity and Critical Thinking: Instruction is now more dynamic than ever. Students have access to online instructional material about almost every subject. The use of these resources should be embraced as an opportunity to expand the focus of our courses, from merely knowledge acquisition to evaluation and synthesis of the material, focusing on their relevance to address local and global challenges. Cross-pollination: Every program has many more courses than a student can possibly take. While students can choose a specific area, they should be presented with the depth and breadth of our field. Pointing out similitudes with other fields, discussing ways to apply theories in other engineering and scientific realms, referring to other courses and professors, and having invited guests from within the department and elsewhere to teach an actual subject and not just giving a seminar, would open students minds to the broad field of engineering, help them identify areas they didn’t know, and see their courses as building blocks of a broader extended universe. CV-building: Every student should leave every lecture thinking “I learned something today”. At the end of a chapter or a section, a student should be able to articulate something they can do now that they weren’t able to do before. By the end of a course, a student should be able to add more skills to their CV to make them realize their growth, and how their time and effort invested in the course will help them in their chosen career paths.

Teaching Experience: I have developed two new courses at UIUC: CEE459-Ecohydraulics and CEE331-Fluid Dynamics in the Environment. CEE459-Ecohydraulics is cross-listed with the Department of Geography and Geographic Information Science as GEOG459, focused on interactions between hydraulic, ecological, and geomorphic processes in river environments at a wide range of spatial and temporal scales, building on the students’ background on fluid mechanics and morphodynamics (Continuity and Cross-pollination). The course includes hands-on experience involving planning, conducting, and analyzing data from laboratory experiments (Creativity and CV-building). The course trains students to assess complex problems involving monitoring, management, conservation and restoration of stream ecosystems (Critical thinking and CV-building). CEE331-Fluid Dynamics in the Environment is a new undergraduate course to teach fluid dynamics tailored specifically for Civil and Environmental Engineering students as a key component of our new BS Degree in Environmental Engineering, substituting the requirement of TAM335-Introductory Fluid Mechanics. In contrast to TAM335, I have designed CEE331 to frame the fundamental notions of fluids in the context of the natural and built environment, to build upon these concepts in other CEE courses (Continuity), with input and participation from faculty in the Water Resources and Environmental areas (Cross-pollination). Lectures and laboratory sessions in CEE331 will foster team-work, experimental design, computational skills, data analysis and interpretation, and technical writing and communication skills (Creativity, Critical thinking). The course will challenge students to apply computational tools to real-world data (CV-Building), providing basis for data-driven computational applications in other courses through the curriculum. CEE331 has been fully approved and will be offered for the first time in Fall 2023, effectively transforming the instruction of fluid mechanics in our Department.

I have taught other 3 courses at UIUC: CEE350-Water Resources Engineering, CEE432-Stream Ecology (cross listed with the department of Integrative Biology as IB450), and CEE555-Mixing in Environmental Flows. I aim to create a common narrative to link the processes and phenomena studied across these courses (Continuity and Cross-pollination). In each course I have included or enhanced a laboratory component to give hands-on experience on experimental design and teamwork (Creativity, Critical thinking). Students collecting their own data encourages posterior data analysis, where they can learn new programming and analysis skills (CV building). Whether hydraulic jumps or Advection-Diffusion equations, students develop a much deeper understanding when they can see the phenomena happening in the lab. I rely on brief quizzes after every lecture to check that the main concept, the “what did I learn today?” question is answered for every student. Using formative and summative assessments throughout the semester helps me adjust directions and monitor student progress, which proved to be a challenge when dealing with students from multiple academic backgrounds in cross-listed courses, to maximize the value that everyone takes out of the course. Team projects throughout the semester allow me to provide just-in-time feedback and identify areas of improvement. Final projects help me assess students’ understanding of the main concepts and their skills at analyzing and interpreting data. Students are encouraged to put extra effort into their projects with my commitment to help them turn it into a conference or journal paper. One team project for CEE459, investigating “Thermal mixing at vegetated stream confluences” was published as part of the Proceedings of the 38th IAHR World Congress in 2019. Students’ evaluation for my courses have been consistently high, being recognized in the “List of teachers ranked as excellent” in Spring 2017 (CEE459), Fall 2018 and Fall 2020 (CEE555). Together with weekly quizzes and unofficial mid-semester evaluations, these assessments help me to exercise a continuous self-reflection on my strengths and weaknesses as an instructor, which helps me improve materials, activities, and delivery of these courses, tailored to the expectations and backgrounds of an ever-evolving student body. I have also had the opportunity to offer short courses at conferences in Latin America, which I tailored into a team effort with some of our senior grad students to develop learning opportunities that provided the participants with useful tools (design, programming, and analysis skills, and use of open source software) for them to use in their careers.

Mentoring experience: At UIUC I have graduated 4 MS students (Thesis option) and 3 PhD students. In Fall 2022, my research group will consist of 2 MS students and 6 PhD students, all of them working on research with a heavy experimental component, developing their skills as scientists and researchers for their academic and professional careers. As a research group, we tailor each student’s program to attain the expertise and profile they envision to pursue their career goals. Our efforts have included collaborations with other research groups to expand the students’ network, and continuous participation in national and international conferences to position them within the scientific community in our field. We provide opportunities to develop outreach activities to engage with and give back to communities outside of academia. Two PhD graduates interested in pursuing jobs in academia are now postdoctoral researchers at leading research institutions: Dr. Jorge San Juan at St. Anthony Falls Lab and Dr. Chien-Yung Tseng at Oak Ridge National Lab. A third graduate, Dr. Andres Prada, is currently a Scientific Specialist at the Illinois Sustainable Technology Center. They all have in common a deep understanding of hydrodynamics processes in aquatic ecosystems. They know how to evaluate such processes, and can communicate the relevance of ecohydraulic challenges to their own research groups to tackle present and future tasks. As they build their own groups and branch out from our ecohydraulics and ecomorphodynamics challenges, they are certainly poised to become future leaders in our field.

Research Statement

Research Statement

Vision: I work towards a paradigm change to understand the feedbacks and interactions between flow and biota at a fundamental level, as part of a physical and biological continuum more complex than the sum of its parts. I envision a substrate-to-surface approach to characterize the interconnected physical and biological processes at multiple scales within dynamic living environments from the sediment-water to the water-air interface, from rivers to coastal areas. Focusing on fundamental hydrodynamic interactions between flow and biota allows us to develop new theoretical frameworks based on turbulent features of the flow, leading to more accurate descriptions of ecohydraulic processes than traditional models which didn’t consider turbulence metrics. Through laboratory experiments, we aim to develop process-based models and predictors to be incorporated in large-scale long-term models of ecosystem alterations and morphodynamic change. Our process-based, substrate-to-surface, continuum approach allows us to address a broad range of ecohydraulic processes and applications, such as river management and restoration, coastal protection, and design and implementation of nature-based solutions.

Research Group: I have built a research group that uses state-of-the-art experimental techniques to better understand flow-biota interactions based on turbulent processes. We aim to (a) develop new models to assess the role of aquatic ecosystems on transport processes, (b) create strategies for monitoring and control of aquatic species, and (c) build theoretical frameworks, leveraged on our understanding of hydrodynamic turbulent processes, to ensure a balance between aquatic ecosystems’ health and the ecosystem services they provide. My research has been funded by local, regional, and federal agencies, totaling $2,823,013 in research funds, from which $1,977,741 correspond to my group at UIUC. Those grants allowed us to conduct unique, novel series of laboratory experiments at the Ven Te Chow Hydrosystems Laboratory (VTCHL) and at the Ecohydraulics and Ecomorphodynamics Laboratory (EEL). Our findings have been published in top leading journals in our field, and have been presented at multiple international conferences where they have been positively received by the community. Recognition from our work in the field of Ecohydraulics and Ecomorphodynamics has allowed me to organize successful special sessions at various conferences since 2016, and being elected to the IAHR Leadership Team of the Ecohydraulics Technical Committee in 2019.

Research Interests: I had previously developed parameterizations for aquatic vegetation effects in streams (Tinoco & Cowen 2013, King et al. 2012), and identified the relevance of vegetation-generated turbulence as the main driver of sediment resuspension for emergent and submerged vegetation, in both fluvial (Tinoco & Coco 2014, 2016) and coastal regions (Tinoco & Coco 2014, 2018), which showed that turbulence-based predictors can be more effective than models based on mean flow. My research group at UIUC has thus branched out to assess the role of turbulent flows on ecosystem functions and services, focusing on characterization of fundamental processes to address: (1) Transport processes through aquatic ecosystems, (2) Control and monitoring of aquatic invasive species, and (3) Hydrodynamic-based frameworks for assessment of ecosystem health.

1. Transport processes through aquatic ecosystems: The overarching theme of my research is to advance the fundamental understanding of physical interactions between flow, aquatic organisms, and their habitat, as we describe in our vision paper in Tinoco et al. (2019). Funded by an NSF-GLD CAREER Award (CAREER - From Substrate to Surface: Quantifying the Impact of Aquatic Vegetation on Exchange Processes, 2018-2023) we characterize transport processes at the sediment-water and water-air interfaces, at the core of the doctoral work of two research group members (San Juan 2021, Tseng 2022). We identified how the biomechanical feedback between flow and plants determines three-dimensional plant motion, creating blade- and leaf-scale eddies from the prone branches near the bed that affects sediment transport capabilities (San Juan et al. 2019). We developed a two-layer model that includes three turbulence sources (from stems, from the bed, and from coherent structures caused by stem-bed-flow interactions) to more accurately predict suspended sediment concentration profiles for streams with aquatic vegetation (Tseng & Tinoco 2021a). Moving from the substrate to the surface, we developed a modified surface-renewal model to predict surface gas transfer rates in vegetated flows based on the production of turbulent kinetic energy by plant canopies (Tseng & Tinoco 2020), and connected both sediment resuspension and gas transfer dynamics by developing a process-based model for gas transfer across the sediment-water-air interfaces in vegetated streams (Tseng & Tinoco 2021b). Our work has helped us understand the links between sediment-oxygen demand and dissolved oxygen dynamics in the presence of benthic populations, which we envision as a key component on improving global carbon budgets for climate change prediction. The laboratory efforts have been complemented by numerical experiments, supported by computational allocations by INCITE at Oak Ridge/Argonne Leadership Computing Facility and NCSA-Blue Waters Awards, focused on resolving three-dimensional features not captured by the laboratory experiments (Ranjan 2018, Ranjan et al. 2022). To develop a full picture from streams to the ocean, we have developed simplified predictors for turbulence metrics for aquatic vegetation under waves, to assess turbulent kinetic energy near the bed and at the top of vegetation canopies, both paramount in the prediction of sediment transport and mixing in aquatic ecosystems (San Juan & Tinoco*, Ch. 3 of San Juan 2021, submitted to JGR-ES). We use such turbulence metrics to build a modified turbulence-based Shields number to predict near bed sediment concentration and develop a simplified exponential model to account for vegetation-generated turbulence and upward convective sediment fluxes from vegetation-bed-wave interactions (San Juan et al.**, Ch. 4 of San Juan 2021, in prep. for WRR). The last pieces of this effort, to adapt our surface gas transfer model to wave conditions and test our predictors against field data are currently underway, directly linked to a New Zealand-Marsden Fund supported collaboration (Bridging the laboratory-field divide to accurately predict the evolution of coastlines) with the University of Waikato and University of Maryland. The Marsden-funded project will allow us to collect data in mangrove forests in the coast of NZ to validate and adapt our predictors to more complex and realistic scenarios.

2. Control and monitoring of aquatic species: Based on our work on flow-vegetation interactions, we identified that a precise description of transport of aquatic species in streams can’t be made from a purely biological approach. Funded by the US Geological Survey (Laboratory experiments on Asian carp eggs and larvae: characterization of settling velocities, drifting response, and survival rate, 2018-2020), working with a team of biologists and hydrologists, we identified the effect of turbulent flow features on survival rates of invasive grass carp eggs and larvae (Prada et al. 2018) and quantified turbulent thresholds that determine whether larvae are attracted or deterred from in-stream structures (Prada et al. 2019, 2021). We also determined how turbulent length scales and turbulent time scales are more relevant than turbulence intensity for larvae to identify shelter regions within aquatic vegetation (Tinoco et al. 2022). The toolset developed during our grass carp studies allowed us to expand in three new directions: 1) to implement our findings on behavioral response of larvae to turbulent flow features in numerical Lagrangian models (e.g., FluEgg), 2) to develop new barriers for control of invasive carp in rivers (project funded by the US Geological Survey, Efficacy of an Oblique Bubble Screen System as a Two-Way Dispersal Barrier for Invasive Carp, 2021-2024), and to assess the response of other invasive species to turbulence features, such as sea lamprey in the Great Lakes (funded by the Great Lakes Fishery Commission. Identifying turbulence features that alter trap efficiency of upstream-swimming lamprey, 2021-2022).

3. Ecosystem health and ecosystem services: As we continue our work to better understand fundamental physical processes and flow-biota interactions, we are establishing collaborations to apply our findings at local and regional scales. Working on a project funded by the Illinois-Indiana SeaGrant Program (Investigating fish energy use and swimming behavior in complex, turbulent flows to guide habitat management, conservation, and restoration in Lake Michigan tributaries, 2018-2021) we identified physiological responses of fish to various types of turbulence features (Strailey et al. 2020) to inform better practices on fish ladders, stream restoration and naturalization. A recently awarded grant from the US Geological Survey with the Illinois Water Resources Center (Enemy of my enemy?: Ecohydraulic assessment of interactions of multiple invasive species in the Upper Mississippi River basin, 2022-2025) will allow us to build a framework to (a) improve understanding of the impact of invasive species on lakes and rivers, including water quality and ecosystem dynamics; (b) identify lake and river characteristics that promote or hinder their establishment; and (c) guide management decisions that will improve water resources at regional scales. A new project with the US Army Corps of Engineers (Evaluation of Micro-Hydro Units for Army Resilience, 2022-2023) will allow us to optimize energy output in shallow-flows turbines, addressing the environmental impact of the micro-hydro deployments. We have ongoing and under review proposals for green infrastructure and nature-based solutions aimed at continuing our work across scales to develop practical solutions to address critical challenges in rivers and coastal cities.
