ECS IE&EE Division member Prof. Mark Orazem (Department of Chemical Engineering, University of Florida) and his student William Watson published their ground-breaking impedance spectroscopy measurement model program, “EIS: Measurement Model Program.” It is available at no cost (for non-commercial use) on ECSarXiv, the Society’s free online service for preprints and other preliminary communications. Orazem began working on the program in the early 1990s. His undergraduate student, William Watson, provided the final key—using Python—to make distribution of the program viable. (more…)

Mark Orazem reflects on now, as opposed to then

Mark OrazemWhen we started on our COVID-19 interview series, no one knew how long the pandemic would last or the long-term impact it would have on our community. As we approach the end of a year of living in the shadow of COVID-19, we thought it useful to follow up with some of our interviewees. We learned that research, collaboration, teaching, and learning are continuing to evolve—along with the challenges of distance learning, meeting, and life.

When we spoke with Mark Orazem last spring about the impact of the COVID-19 pandemic, he was on a sabbatical that did not turn out as planned. Now he is back teaching at the University of Florida where he is Distinguished Professor in the Department of Chemical Engineering. (more…)

Adjusting to a Changed World

Mark Orazem on a Sabbatical that Doesn’t go According to Plan

In our series, The ECS Community Adapts and Advances, Mark Orazem recounts how he made good use of a sabbatical year that didn’t turn out to be anything like he expected. Currently Professor of Chemical Engineering at the University of Florida (UF), he was officially on leave for the 2019-2020 academic year. He is returning to a very different environment than he left a year ago. (more…)

Two ECS Members Win Professorship Awards

Two key ECS members have recently received prestigious professorship awards from the University of Florida’s Department of Chemical Engineering. The department has recognized Mark Orazem and Fan Ren for their outstanding commitment to education and innovative research in chemical engineering.

Orazem_2011_cmykMark Orazem was awarded the ExxonMobil Gator Chemical Engineering Alumni Professorship for his excellence in research and tremendous impact in academia. Orazem, an ECS Fellow, joined the Society in 1978 and has previously been recognized for his excellence in student impact in 2012 when he received the ECS Henry B. Linford Award for Distinguished Teaching.

Orazem is a recognized expert on impedance spectroscopy. His research helps to provide valuable insight into such diverse systems as batteries, fuel cells, corroding metals, and human skin. His research ranges in scope—from assisting in the development of biosensors for companies such as Medtronic to engineering dewatering mining waste streams for Mosaic. He served for ten years as an associate editor for the Journal of The Electrochemical Society and authored the seminal Electrochemical Impedance Spectroscopy.

(PS: You can take a course instructed by him at the 228th ECS Meeting!)

Ren_FanFan Ren was awarded the Fred and Bonnie Edie Professorship, representing the highest standards of chemical engineering and serving as a role model for students. Ren is an ECS Fellow and an active member of the ECS Electronics & Photonics Division.

His groundbreaking research centers around electronic material and devices, where he pioneered the use of wide bandgap semiconductor sensors for chemical and biological detections. His acceptance lecture upon receiving the Gordon E. Moore Medal for Outstanding Achievement in Solid State Science and Technology in 2013 focused on this topic of researcher, detailing the cross-section between semiconductors and biosensors for medical applications such as glucose monitoring, biomarker detection for infectious diseases, and cancer diagnosis.
