Hannah Campbell receives 2020 Subramanian Thesis Award

May 26th, 2020 by Johnson, Abby T (UI Health Care)

Hannah Campbell, who completed her PhD with Dr. Kris DeMali, was awarded the 2020 Subramanian Award for the best PhD thesis in the Department of Biochemistry. The Subramanian Award is made possible by a gift from Dr. Alap Subramanian, a 1964 PhD student 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-Institute.

Dr. Campbell’s thesis was entitled, “Mechanisms of E-Cadherin Force Transmission.” Hannah received her PhD in August 2019 and is currently an Applications Scientist at Integrated DNA Technologies in Coralville, Iowa.

 

Congratulations Dr. Campbell!

Three Undergraduate Students Awarded 2020 Rex Montgomery Scholarships

May 14th, 2020 by Johnson, Abby T (UI Health Care)

The 2020 Rex Montgomery Scholarships were awarded to:

  • Geoff Collins, Dr. David Price’s laboratory
  • Dariya (Dasha) Kozlova, Dr. Brandon Davies laboratory
  • Cade Rahlf, Dr. Madeline Shea’s laboratory

Rex Montgomery Scholarships recognize sophomore or junior undergraduate students for their outstanding academic record and commitment to research. The purpose of this scholarship is to ease the recipient’s financial load at the University of Iowa during his/her undergraduate education and research training.

This scholarship was established in 2014 by the late Dr. Rex Montgomery, Professor Emeritus of the Department of Biochemistry. Dr. Montgomery began his career at the University of Iowa in 1955, and was admired for his impact as a researcher, teacher and mentor. Dr. Montgomery was an internationally recognized carbohydrate biochemist and textbook author. While on the faculty, he served as Associate Dean for Academic Affairs in the College of Medicine, the Vice President of Research for the University and was the founding director of the University of Iowa Physician Assistant Program. Dr. Montgomery retired in 2005 after more than 50 years on the faculty.

Brianna Lupo and Francesca Spencer awarded Montgomery Scholar’s Prizes

This prize was established by mentees, colleagues and friends of the late Dr. Rex Montgomery, Professor Emeritus of the Department of Biochemistry. Dr. Montgomery began his career at the University of Iowa in 1955, and is admired for his impact as a researcher, teacher and mentor. Dr. Montgomery is an internationally recognized carbohydrate biochemist and textbook author. While on the faculty, he served as Associate Dean for Academic Affairs in the College of Medicine, the Vice President of Research for the University and was the founding director of the University of Iowa Physician Assistant Program.

The Whittmann and Khorana Scholar awards

May 14th, 2020 by Johnson, Abby T (UI Health Care)

The Wittmann and Khorana Scholar awards are given to a male and female Biochemistry major, respectively, recognizing their exceptional understanding of biochemistry and its value to society.

Nick Shaw won the 2020 Professor H.G. Wittmann Scholar Award. Nick did research in the Wallrath lab.  After graduating, he will be continuing to perform research in the Wallrath lab on nuclear envelope-related myopathies.  Next fall, he will be pursing a position at UIHC that involves patient interactions, with plans of attending medical school in the near future.

Emeleeta Paintsil won the 2020 Professor H.G. Khorana Scholar Award.  Emeleeta did research in the Spies lab examining the functions of RAD52 on replication fork remodeling enzymes.  She will be attending the Medical College of Wisconsin in the fall to pursue a Ph.D. in their Interdisciplinary Doctoral Program in Biomedical Sciences.

These awards are sponsored by Dr. Alap Subramanian.  Dr. Subramanian earned his Ph.D. in Biochemistry from the University of Iowa in 1964 studying with Dr. George Kalnitsky.

 

Congratulations Nick and Emeleeta!

Jacintha Thomas featured on UIHC “The Loop”

May 7th, 2020 by Johnson, Abby T (UI Health Care)

Jacintha Thomas, a Research Assistant in Dr. Lori Wallrath’s lab, was featured in the May 7th UIHC publication called “The Loop”. During the COVID-19 shut down, Jacintha divides her time between the adjacent laboratories of Lori Wallrath and Arlene Drack (Ophthamology and Visual Sciences). Jacintha has been instrumental in maintaining valuable mice and fruit fly stocks used for studies of human disease.

 

The Loop article can be found here.

 

Thanks Jacintha!

Brian Krueger at forefront of COVID-19 DNA testing

May 7th, 2020 by Johnson, Abby T (UI Health Care)

Brian Krueger, Associate Vice President, Technical Director, R&D, LabCorp and a 2009 PhD graduate of the Department of Biochemistry, has been at the forefront of COVID-19 DNA testing. On January 12, 2020, China published the first DNA sequence of the coronavirus genome from patients with COVID-19. By March 16, 2020, in unprecedented record time, Dr. Krueger and his co-workers developed the first FDA Emergency Use Authorization (EUA) approval for a clinical DNA diagnostic test. On April 21, 2020, they were the first to receive EUA approval for the first at-home test kit based on nasal swabbing. We are proud that a Biochemistry alumnus is helping to keep our country safe.

Thank you Dr. Krueger!

Francesca Spencer coauthored a paper published in Nature Scientific Reports

May 7th, 2020 by Johnson, Abby T (UI Health Care)

Francesca Spencer, graduating senior in Biochemistry and Italian at the University of Iowa, is coauthor of a paper appearing in Nature Scientific Reports. She collaborated with a group of scientists and students from the University of Keele, U.K., led by Dr. Jamie Pringle, and helped analyzing data from a  very long study (longest globally, starting in Dec. 2007 and still ongoing) of geophysical monitoring of simulated clandestine burials on the Keele campus using pig cadavers as human proxies. This study will be crucial as it will tell forensic search practitioners a) which geophysical technique is optimal to use to find a body in different timeframes after death/burial, b) optimal equipment configuration(s) for body detection and c) provide comparable datasets for them to see what anomalies should be looking like, and thus where to dig. Dr. Pringle has applied this methodology to unsolved cold cases in Wales and participated in international collaborations to locate mass graves from the Spanish Civil War. Ms Spencer plans to continue her studies next year focusing on Forensics as a graduate student at the University of Utah.

The article entitled, “Geophysical monitoring of simulated homicide burials for forensic investigations” can be found here.

 

Congratulations Francesca!
