Lacy Barton receives 2015 Subramanian Thesis Award

Thursday, September 24th, 2015

Lacy Barton, who completed her PhD with Dr. Pamela Geyer, has been named the 2015 Subramanian Award for best PhD thesis in the Department of Biochemistry. Lacy is currently a postdoctoral fellow in Ruth Lehmann’s laboratory at New York University School of Medicine in New York, NY. She was recently awarded a Damon Runyon Cancer Research Foundation Fellowship for her project entitled “Mechanisms of directed cell migration in a complex in vivo environment.” Damon Runyon fellowships are among the most recognized postdoctoral awards and a high accolade for an early career scientist.

Lacy  is the 22nd winner of the Subramanian Award, which is made possible by a gift from Dr. Alap Subramanian, a 1964 PhD from the department, who parlayed his training with the late George Kalnitsky, (and with Irving Klotz at Northwestern and both Bernard Davis and Herman Kalckar at Harvard Medical School), into a highly successful career at the Max-Planck-Institut. Our deepest thanks to Dr. Subramanian and our heartiest congratulations to Dr. Barton.

Wednesday, May 21st, 2014

The 2014 Midwest Chromatin and Epigenetic Meeting was held on May 18, 19, and 20 at the Wisconsin Institutes for Discovery (WID) at the University of Wisconsin-Madison.

Speakers from the University of Iowa included Frederick Domann, Catherine Musselman, Pamela Geyer and Lori Wallrath; poster presenters included Lacy Barton, Heather Brockway, Diane Cryderman, Lynne Dieckman, Daniel Ferrell, and Tyler Weaver.

Over 200 attendees, representing eighteen states and four countries, presented their current research findings on transcriptional regulation, chromatin structure, and epigenetics as it relates to nutrition, the environment and human disease.

The prestigious Journal of Biological Chemistry‘s Herb Tabor Young Investigator Award was given to Andrew DeVilbiss, a graduate student at the University of Wisconsin.

Dr. Wallrath co-organized the event with John Denu of the University of Wisconsin and Raul Urrutia of the Mayo Clinic.

Geyer Lab finalist in the Image Award Competition at the 55th Annual Drosophila Research Conference

Thursday, April 3rd, 2014

Dr. Pamela Geyer’s laboratory was recognized as a finalist in the Image Award Competition at the 55th Annual Drosophila Research Conference for an image generated by graduate student, Lacy Barton.  The award is given to the most striking image that clearly conveys a point of important biological information.  The image submitted captures the developmental defects in female germline stem cells resulting from loss of the nuclear lamina protein Otefin. This figure was published in the the Barton et al., Developmental Cell in 2013. The winning image and other finalists images can be viewed at Barton Image

Geyer receives 2013-14 Graduate College Outstanding Faculty Mentor Award

Tuesday, March 25th, 2014

Congratulations to Professor Pamela Geyer who has been selected as the recipient of the 2013-14 Graduate College Outstanding Faculty Mentor Award in the Biological and Life Sciences. Professor Geyer has demonstrated excellence in a wide variety of mentoring functions over the past two and a half decades at the University of Iowa. In her own laboratory, Professor Geyer has directed the PhD and Masters thesis research of 13 graduate students and trained an additional 47 first year rotation students. She has served on the PhD thesis committees of 39 graduate students from a wide variety of Departments and Programs in the Carver College of Medicine and the College of Liberal Arts and Sciences. She has played key leadership roles in the interdisciplinary graduate programs of Genetics and of Molecular & Cellular Biology, and she is a long-serving director and co-director of the Medical Scientists Training Program. She played a major role in reshaping the graduate student curriculum for all students in Bioscience-aligned programs. Thus, her impact on graduate education has been enormous. Her direct and indirect mentorship has produced a cohort of University of Iowa scientists and physicians, who are exceptionally well trained and have succeeded in becoming faculty members, research scientists, physician scientists, and other accomplished professionals. Professor Geyer is a paragon graduate mentor and a role model for all of us engaged in graduate education.
