Ardythe McCracken, Ph.D.

Foundation Professor Emeritus

Summary

I joined the Department of Biology at UNR in 1987, where I developed and taught courses in Cell and Molecular Biology for undergraduate non-science majors, biology majors, and graduate students.  I found that teaching molecular cellular biology was a challenge due to the exponential growth of knowledge in this field, yet working with the many bright students in my classes was extremely rewarding.  For my teaching efforts I twice received nominations for the Board of Regents' University Teaching Award, twice was a finalist for the College of A&S Teaching Excellence Award, and was also a College of Science Outstanding Teaching award finalist.  In 2000, I developed an accelerated combined BS/masters degree program in Biotechnology, in 2002, I was awarded the University of Nevada Foundation Professorship, and in 2005, I was identified as a Senior Scholar Mentor. 

During my tenure at the 推荐杏吧原创, my research program was supported by grants and awards from UNR, Reno Cancer Center, ACS, Cystic Fibrosis Foundation, NIH, and NSF.  Among these, was a career development award supporting a summer research fellowship at UC Berkeley with Randy Schekman and a sabbatical at the University of Melbourne with M-J Gething.  Additional international research seminars, research collaborations, and teaching courses in protein trafficking, took me to Spain, Hong Kong, Russia, Australia, Slovenia, Croatia, New Zealand, three universities in South Africa, and several universities in the USA.  Together with graduate students, postdoctoral fellows, international collaborators, and undergraduate research students, we published 32 scientific papers in refereed journals, 3 book chapters, 57 abstracts in conference and symposium proceedings, and numerous invited reviews, reports, and news articles.  

As a scientific advisor, I benefitted from assignments at the Finish Academy of Science, Israel Science Foundation, University of Cape Town-South Africa, University of Pittsburg, Jefferson University Med Sch., Wiley and Sons Publishing, Boise State University, Penn St. University, The Educational Testing Services- Graduate Record Exam, NIH, NSF, and various cell and molecular biology scientific journals.  At the University, I served on numerous search committees for faculty and administrators, selection committees for faculty and student research awards, and served on the National Scholarship task Force.  At the end of my career I was awarded a Fulbright Senior Scholar in Molecular-Cellular Biology to Northern Caribbean University, Jamaica; where I worked with undergraduate students to prepare them for graduate school in the US and advised faculty towards the enhancement of their graduate programs. 

Recently, I was honored by an invitation to contribute an article for the Encyclopedia of Cell Biology, 2016,  a product of a global collection of editors and contributors organized by the American Society of Cell Biologists.  ASCB is a network of about 9,000 cell biologists in more than 62 countries.  Editors from this worldwide community chose topics covering every aspect of cell biology and invited the experts in each field to author articles for the encyclopedia.  I am extremely privileged to have been selected to contribute an article on my research findings completed during my tenure at UNR.  The first listed publication is the product of that invitation.  Several of the earlier publications in the list of Selected Publications describe the findings made by my research associate, students, and me that led to the discovery of ER associated degradation (ERAD).
