Dr. Ritter received his B.Ch.E. degree from the City College of New York, and his M.S. and Ph.D. degrees in Ch.E from the University of Rochester. Before returning for his Ph.D. degree he had over 10 years of industrial experience in the aerospace industry for the U.S. Navy and United Aircraft in solid rocket propellant development and as a development engineer for the Mixing Equipment Company and the DuPont Co. His first academic appointment was at Stevens Institute of Technology in the department of Chemistry and Chemical Engineering where he did research on solar energy storage and conversion and optimal control of chemical processes. He taught courses in transport phenomena and process control. While at Stevens he met Francis Chinard, MD from UMD-New Jersey Medical School and started collaborative research in pulmonary transport and metabolism in-vivo. This led to a full time position in Dr. Chinard’s lab in the department of Medicine at NJMS. After a few years he was recruited to the department of Physiology where he spent the next 20 years teaching Cardiovascular and Respiratory physiology, statistics for the life sciences and physical chemistry to Medical, Dental and Graduate students. His research areas were microcirculatory and cardio-respiratory physiology. He was course director of the medical physiology course for five years before returning to Stevens to start the Biomedical Engineering program. He was the PI or Co-PI on grants from NSF, NIH, AHA, and New Jersey Commission on Science and Technology.
Dr. Ritter has mentored nine Ph.D. students in Physiology and Biomedical Engineering and over 40 Masters student’s in Biomedical Engineering.
He is the co-author of over 45 publications in peer reviewed journals and numerous abstracts and presentations at local, national and international conferences. He is the primary author of an undergraduate textbook in Biomedical Engineering.
His current research interests are in Systems Physiology, Rotary Protein Motors, The Failing Heart, and Biorobotics.
He has recently started a Biorobotics and minimally invasive surgery lab in collaboration with surgeons at Hackensack University Medical Center (NJ).

A Comparative Study of Classroom Learning and Online Learning on Medical Imaging with Computer Lab ExercisesAbstract“Medical Imaging” is an important subject in most bio-medical and bio-engineering curricula. Itis a multi-discipline subject involves studies in biology, physics, mathematics, electricalengineering, and computer science. To effectively offer this as an introductory undergraduatecourse, we designed a series of computer lab exercises for students to observe the computationaland physical processes of medical imaging modalities, and to practice computing skills on bio-medical signal processing. The software development is partially supported by an NSF CCLIgrant."Medical Imaging" is a required course in the undergraduate BME program at Stevens Instituteof Technology. This course is offered each year in Fall semester as a regular on-campus course,and in Spring semester as an on-line course. We started the deployment and assessment of theselab exercises in Fall 2008, and by May 2010 we have obtained the assessment results for twoconsecutive years. These results enable us to study student learning behaviors and performancein many different ways. In particular, we attempt to have a comparative study on studentexperience in these computer-based lab exercises during the regular on campus sections andduring asynchronous online sections.Our assessment is currently based on student survey. We designed a simple set of surveyquestions for students to complete after each lab exercise. The questions include the scales ofstudent's understand of a certain concept before and after the lab exercise, the scale of knowledgepreparation for the lab exercise, the time spent on the lab exercise, and the need for lab designimprovement.In this study we introduce two metrics based on the survey results: perceived performanceimprovement index (PPII) and normalized difficulty index (NDI). We compare the PPIIs andNDIs of students from two on-campus sections and two online sections. Our overall observationindicates that students perceived similar learning experience from these two teaching modes.This finding is indeed encouraging in term of promoting online learning.In our final paper we will report the details of these two learning modes, the analysis of allassessment results, and some discussions on the differences between the learning experiencesand performances of these learning modes.
