Teaching Statement

My philosophy on teaching is based on the fundamental belief that I am entrusted with the responsibility to both pass on and model tools and values that will benefit the students not only in their engineering career, but, if I am truly successful, throughout the course of their lives.  This philosophy was formed in a large part by observing my mentor, the late Professor Ben Chie Yen.  His patient, thought-provoking guidance and instruction provided a foundation that continues to direct my thinking and career goals.  He patiently and purposefully combined instruction, his example, and, most importantly, guidance so his students would learn by experience. This teaching was not limited to the scope of our academic endeavors; he provided skills of great value in both my professional and personal communities.  I hope to follow this extraordinary example in my career as an educator and mentor.


Among the tools that I am entrusted to pass on to my students, foremost in both my classroom instruction and in guiding student research, is developing the logical reasoning necessary to successfully address the widely varied problems they are likely to face in their careers.  The logical reasoning includes the ability to critically analyze a problem, to synthesize the details of the problem with other information and experience, to apply their integrated knowledge and experience to develop alternative approaches to address the problem, to logically evaluate strengths and weaknesses of the alternatives, and to clearly communicate the process and resulting conclusions.  As a teacher, I need to discern the knowledge, experience, and skills of my students and adapt my instruction and expectations to incrementally improve their ability to implement this logical reasoning process.


I believe that I need to constantly adapt my teaching to reflect student feedback, particularly to ensure that my teaching is appropriate to the knowledge, experience, and skills of my students.  In order for this to be timely and effective, this feedback cannot be limited to students’ performance on assignments and examinations; I must routinely provide a variety of avenues to obtain this feedback and these avenues should encompass a variety of learning styles.  In keeping with this belief, I incorporate many opportunities for student feedback throughout my classroom teaching.  Some of the feedback opportunities I incorporate into my teaching include:

·             Planned active learning exercises into each day’s lesson plan; both to obtain student  feedback and to “reset the attention clock;”

·             Included an on-line discussion area, which gives the students an ‘around-the-clock’ forum to post questions, respond to other queries or responses, and see (and comment on) my responses;

·             Incorporated a 5-minute break into each lecture, which works to provide those students who are not comfortable commenting in front of the class an opportunity to ask questions;

·             Included an informal early feedback evaluation of the course and my teaching; and

·             Provided comment cards and a comment box at the exit of the classroom and allocate time at the end of each lecture for the students to write any comments/questions about the course, the material covered, etc.

·             Developed on-line quizzes to provide quick feedback to me and to the students.  These always include a “muddiest point” question where the students communicate the portion of the recent material where they would like further clarification.


I intentionally stay abreast of contemporary issues related to the material that I am teaching.  This is not limited to advances in research, but also common professional practice.  For example, while teaching the surface drainage course I routinely follow the discussions in on-line forums sponsored by the major providers of surface-drainage software.  This allows me to identify common misconceptions and errors in surface-drainage design and to provide my students with the knowledge and understanding to correctly address these issues when they arise in their careers.




I believe that my teaching needs to provide students with resources that will be beneficial in their careers.  My goal is that the text and supplemental reference materials from my courses will become worn out with use over the course of the students’ careers.  Selecting these materials should balance the utility of the material with the cost to the students and the Department.  I continue to explore options to better provide reference materials to the students.  I used a custom, electronic text that I developed with Prentiss-Hall one semester (a failed effort, based on student feedback).  Because of the feedback, the next time I taught this course, I posted reference materials from a variety of sources to the Compass site (much better reception from students).


Dr. Schmdit has been active in providing on-line as well as on-campus instruction for the past 10 years.  His course CEE 453 has been one of the Department’s on-line courses since 2006.  He has also taught CEE 551 and CEE 598 IUW for the CEE-Online program.  In the course of teaching these ourses, he has developed means to provide on-line office hours, using Lync and Adobe Connect software, so that on-line and on-campus students and interact synchronously for office hours, as well as providing recordings of office hours for students to access asynchronously.

Research Statement

Dr. Schmidt's research interests are in the study of surface-water hydraulics and hydrology, with particular emphasis in two areas: (1) providing better understanding of the hydraulics and hydrology of urban storm-water management systems and (2) provide improved measurement and quantitative description of streamflow and related parameters, including quantification of the uncertainty in the reported values. 


In the area of urban hydrology and hydraulics, Dr. Schmidt’s research seeks develop improved methods to simulate the complicated hydrologic and hydraulics processes in complex urban environments, to develop methods to quantify the effect of various Sustainable Urban Drainage System (SUDS) practices on the hydrology and hydraulic behavior of urban systems, and to develop and apply improved sensors for hydraulic measurements, particularly in complex environments such as urban and agricultural systems.  Dr. Schmidt and his students have developed new numerical models to simulate the hydrologic and hydraulic response of urban drainage systems.  In particular, his team has developed probabilistic urban models for catchments where the data describing the hydrologic properties of the catchment and the hydraulic parameters of the drainage system are too sparse to allow a deterministic model.  He and his students have developed a system of models that allow different levels of sophistication depending on the objectives of a given study and applied these to a study of the drainage system for the 970 km2 watershed served by the Tunnel and Reservoir Plan in Chicago.  This system allowed fast simulations coupled with a genetic-algorithm optimization to examine real-time control rules for stormwater gates and pumps, yet also could provide simulation of hydraulic transients in the tunnel system.  This system continues to be expanded, with on-going research to incorporate sophisticated small-scale simulations of the hydrologic response of SUDS practices (green roofs, rain gardens, etc) into both probabilistic and deterministic catchment models and apply these to examine the impacts of SUDS at the catchment scale and under potentially changing climate scenarios.


In the area of developing methods to provide improved measurement and quantitative description of streamflow and related parameters, Dr. Schmidt is working to study new methods to apply multi-platform sensor systems (e.g., LiDAR, GPS, ADCP, water-quality sensors) to measure entire reaches of streams, to merge the data from the different sensors, and then to use the resulting data base to improve the analysis and understanding of entire reaches of streams.  Dr. Schmidt has applied these tools to provide fine resolution maps of shear stress, habitat suitability, and hydrokinetic power potential and is currently developing tools to apply these tools to provide better calibration and validation of 2-D and 3-D hydrodynamic models.

Undergraduate Research Opportunities

In the past three year Dr. Schmidt has supervised eight undergraduate students doing REU research on topics including examining data from monitoring rainfall on and runoff from conventional and green roofs,modeling sustainable urban drainage systems, examining uncertainty in different measurement methods utilizing acoustic Doppler current profilers (ADCPs), and developing probabilistic methods to optimally schedule sewer maintenance.
