Welcome Dr. Rahman

Rahman family
Mohammad Rahman at his Ph.D. graduation ceremony in Nagoya University, Japan with his wife and son in traditional Japanese dress.

Mohamad Rahman, Ph.D., joined the Department of Biochemistry and Molecular Biology as an Assistant Professor in August 2021. Find out more about him with this Q&A.

  • Where are you from and what do you miss most? I am from Bangladesh. I miss my childhood. I wish I could go back to my middle school and meet my friends.
  • Fun fact about yourself. I wanted to serve as a fighter pilot in the Bangladesh Air Force (BAF). I was rejected during my enrolment as a cadet in the BAF due to my compromised eye power. Then I became a biologist. Now I feel fortunate for my rejection from the BAF, which allowed me to explore the fascinating mysteries and fun of biology.
  • What is your favorite place you’ve lived? I completed my undergraduate education in Bangladesh. I moved to Nagoya in Japan for my Ph.D., and stayed there for six years. Then I moved to New York, and stayed there six years more for my Postdoctoral training, prior to my moving in Little Rock. So far, Nagoya is the most favorite place I have ever lived.
  • What place you would like to visit? I would like to visit Melbourne.
  • Do you like to cook? What is your favorite recipe? I love to cook. I enjoy cooking South Asian cuisines. My favorite recipe is Mutton Biryani.
  • What is your favorite food? I love hot and spicy foods. My most favorite food is Mutton Biryani.

Congratulations Dr. Schleiff

Allie Schleiff

On July 12, 2021, Mary “Allie” Schleiff successfully defended her dissertation entitled “Diphenylamine NSAIDs are Bioactivated into Hepatotoxic Quinone-Species Metabolites”. Dr. Schleiff was mentored by Dr. Grover Paul Miller and was a trainee of the Systems Pharmacology and Toxicology (SPaT) T32 program. As a graduate student, she was an author on 15 publications, 6 of them first author. Moreover, she gave 24 oral and poster presentations, including invited talks. Based on her research efforts, she received 11 awards including Top 10 Finalist for the Sternfels Prize in Drug Safety Discoveries (2020), Third Place for the Bhuvan Award for Excellence in Biochemistry Graduate Research at UAMS (2021), and the Drug Metabolism and Disposition Highlighted Trainee Author by the American Society for Pharmacology and Experimental Therapeutics (2021).  Allie has since taken a position as a postdoctoral fellow with Drs. Qin Shu and Daniel Willett at the FDA Center for Drug Evaluation and Research in St Louis, MO.

UAMS Translational Research Institute Names Six Entrepreneurship Scholars

The UAMS Translational Research Institute (TRI) Health Sciences Innovation and Entrepreneurship (HSIE) Postdoctoral Training Program has named six postdoctoral scholars for its class of 2023. The scholars, selected in a competitive application process, will begin two years of mentored entrepreneurship training July 1.

The program, which includes stipends up to $57,000 per year, is designed to help promising scientists more quickly move their discoveries into everyday practice by teaching them commercialization and team science skills.

The HSIE Postdoctoral Scholars – all from the UAMS College of Medicine – their research project plans and mentors are:

Laura Ewing

Laura Ewing, Ph.D., Department of Biochemistry and Molecular Biology and Winthrop P. Rockefeller Cancer Institute. Her project will focus on identifying predictors of the development, progression or recurrence of different types of ovarian cancer.
Mentor: Michael Birrer, M.D., Ph.D.

Kindann Fawcett

Kindann Fawcett, Ph.D., Department of Pediatric Neurology at Arkansas Children’s Hospital (ACH). Her project will focus on development of a tool to assess risk and best practices in regards to nutrition and its role in the standard care provided for patients at ACH and UAMS. Secondly, she will focus on the creation of a digital media and virtual, interactive learning platform for nutrition and exercise curriculum to educate the youth of Arkansas.
Mentor: Aravindhan Veerapandiyan, M.D.

Tiffany Miles

Tiffany Miles, Ph.D., Department of Neurobiology and Developmental Sciences.
Her project will focus on hormonal deficiencies related to obesity and then establishing a platform to educate Arkansans on the impact of maternal nutrition in offspring development.
Mentor: Angus MacNicol, Ph.D.

Thomas Nienaber

Thomas Nienaber, M.D., Department of Pediatrics – Division of Neonatology. His project will address improving the neonatal mechanical ventilation by optimizing the endotracheal tube.
Mentor: Kevin Sexton, M.D.

Megan Reed

Megan Reed, Ph.D., Department of Biochemistry and Molecular Biology. Her project will focus on the use of comparative transcriptomics pipeline to generate and validate patient-specific treatment options for glioblastoma tumors.
Mentors: Alan Tackett, Ph.D., and Analiz Rodriguez, M.D., Ph.D.

Julia Tobacyk

Julia Tobacyk, Ph.D., Department of Pharmacology and Toxicology. Her project will focus on the development of new treatments for opioid use disorder in pregnancy.
Mentor: Lisa Brents, Ph.D.

The program, which includes stipends up to $57,000 per year, is designed to help promising scientists more quickly move their discoveries into everyday practice by teaching them commercialization and team science skills.

It is supported by the NRSA Training Core (TL1) component of the UAMS Clinical and Translational Science Award, grant TL1 TR003109.

“Our program goal is to accelerate biomedical discoveries to improve health and health outcomes,” said Nancy Rusch, Ph.D., who co-directs the program for the UAMS Translational Research Institute. “I am very enthusiastic about this group of scholars. They all have exceptional talent and they are pursuing projects than can make a real difference.”

The HSIE Postdoctoral Training Program has traditionally provided support annually for eight postdoctoral fellows (four in each year of the two-year program).  However, this year the program was able to admit a clinical fellow in addition to five postdoctoral fellows. The expansion relied on postdoctoral stipends provided by the Winthrop P. Rockefeller Cancer Institute, the Arkansas Children’s Research Institute, and the Department of Pediatrics – Division of Neonatology. The program curriculum represents a partnership between the UAMS Translational Research Institute and the Entrepreneurship Graduate Program in the Sam M. Walton College of Business at the University of Arkansas, Fayetteville.

In addition to Rusch, professor and chair of the Department of Pharmacology and Toxicology and executive associate dean for research in the College of Medicine, the program’s leadership team includes co-director Kevin Sexton, M.D., associate professor in the Department of Surgery, and Nancy Gray, Ph.D., president of BioVentures and professor in the Department of Pharmacology and Toxicology. Pamela Kahler is program manager.

The first group of HSIE Scholars named in July 2019, who will be graduating from the program this spring are: Melody Greer, Ph.D. (mentor, Fred Prior, Ph.D.), Samir Jenkins, Ph.D. (mentor, Robert Griffin, Ph.D.), Astha Malhotra, Ph.D. (mentors, Amanda Stolarz, Pharm.D., Ph.D.; and Jawahar Mehta, M.D., Ph.D.), and Aaron Storey, Ph.D. (mentor, Rick Edmondson, Ph.D.).  The second group of HSIE Scholars named in July 2020 are: Emilie Darrigues, Ph.D. (mentor, Analiz Rodriguez, M.D., Ph.D.), Shana Owens, Ph.D. (mentor, Craig Forrest, Ph.D.), John Sherrill, M.P.H., Ph.D. (mentor, David Bumpass, M.D.), and Zachary Waldrip, Ph.D. (mentor, Marie Burdine, Ph.D.)
