Volunteer - Senior Research Associate

Cecile Martin (2017-2018) - Cecile was instrumental in setting up the lab and initiating our CRISPR project. She is now a Scientific Illustrator at Graphit Science & Art, LLC

Adel Ghnenis - Post-Doc - Now at University of Michigan

Adel comes all the way from Libya. He was initially trained as a Veterinarian, at the University of Tripoli, Libya. After that, he completed a MSc. at the University of Manchester, United Kingdom, on Molecular Parasitology, where he investigated the expression and stability of parasite antigens and DNA. He moved to the US, University of Wyoming, and obtained his Ph.D. in Animal and Veterinary Science. He evaluated the impacts of maternal nutrition during early gestation on fetal growth and development as well as offspring health and productivity. He examined the glucocorticoid metabolism pathways and evaluated the expression of 11β-hydroxy steroid dehydrogenase system in different tissues including placental, heart, liver, and adipose tissues. He also investigated fibrosis in the liver and heart of maternally obese/ nutrient restricted offspring. Adel then joined Jared Bushman's lab (University of Wyoming) for a brief postdoc, where he studied sex and diet-dependent metabolic changes occurring after spinal cord injury.


Adel's main research interest is to better understand the systemic cardio - metabolic alterations that occur in chronic SCI and develop effective therapeutic interventions to reduce major health issues associated with SCI, using drugs and genetic tools to target specific signaling pathways. He's also involved in projects characterizing how SCI can induce bowel dysfunction and finding ways to re-activate the colonic activity.

He loves playing (and watching) soccer! Allez les bleus! (ok, maybe he's not cheering for the French...yet)

Research Assistants

Alexandra Lopex - Research Assistant / Lab Manager -Now Graduate Student - UT Southwestern

Alexandra Lopez received her B.S. in Biology and a minor in mathematics in 2018 from Texas A&M University. During her undergraduate career, Alex worked in Dr. Brett Mitchell’s lab investigating the role of the lymphatic system in the development of various forms of hypertension.

Right after graduating, Alexandra joined the Geoffroy lab as a lab manager. She was tremendously helpful with all the day-to-day needs and made sure the lab run smoothly, and safely! One of her projects was to determine the protective and regenerative properties of a test compound in the dorsal hemisection model of spinal cord injury.

Alex hopes to one day work at Texas Children’s Hospital as a medical scientist developing immunomodulatory therapies for childhood diseases.

During her free time, Alexandra enjoys running, spending time with her friends and family, and playing with her two dogs, Snoopy and Millie.

In his free time, Austin enjoys working out, spending time with close friends and traveling.

Ana Mathew - now M.D. candidate, 2024


As a Public Health major and Neuroscience minor, Ana Mathew has developed a passion for research since her first semester at Texas A&M. In her current role, as an undergraduate researcher in the lab, she is involved in a pre-clinical drug testing project (in collaboration with Axoltis). She is testing how this particular drug can promote functional recovery after spinal cord injury (focusing on the BMS open field test). Additionally, she is assessing the effect of the drug on demyelination/remyelination as well as the inflammatory response. Her previous research topics include prenatal health and understanding the growth in aging populations with the School of Public Health.

In her free time, you can catch her watching Game of Thrones, making gluten-free desserts, and spending way too much time on Pinterest. 


Sonali Batta - M.D. Candidate, 2023

Sonali received her Bachelor's in Biology from The University of Texas at Dallas in 2017, where she studied vitamin A deficiency in Bangladeshi youth. She then received her Master's in Nutrition from Texas Woman's University in 2019, where she worked with a non-profit organization delivering fruits and vegetables to under-served communities. She researched the organization's impact on nutritional and clinical parameters of the communities served. She is currently a first-year medical student here at Texas A&M College of Medicine and she is assessing the anatomical changes of the bowel following spinal injury. When she has free time, she enjoys watching TV, taking short road trips, going for walks, and trying out new places to eat. 


Joshua Benton

Josh is a member of Texas A&M’s class of 2021, receiving a B.S. in  Biomedical Science with a Minor in Business. He’s working on different projects aiming at finding drugs able to promote axon regeneration in middle-age mice after spinal cord injury. He plans to attend medical school through the Air Force after receiving his undergraduate degree. He hopes to work in flight medicine to support airmen like my father who is a pilot.
Outside of the lab, he is part of a service organization as well as a Co-Chair for Fish Camp to welcome the Class of 2024. He’s also a weightlifter and wakeboarder in his free time.


Lily Kuhlman  - MD candidate, class 2025

Lily Kuhlman is a member of Texas A&M’s class of 2021 and is from Houston, Texas. She is working towards a B.S. in Biology and Genetics. She joined the lab in the Fall of 2018. Lily is currently involved with the testing of a drug, in collaboration with a biotech company (Axoltis), to determine if this drug can promote functional recovery after spinal cord injury (using the activity chamber system). She is also assessing if this treatment can enhance neuroprotection, axon regeneration and reduce the injury site.

She would like to do medical outreach either domestically or abroad. Outside of research, she is involved with her women’s organization, and enjoys spending her spare time outdoors or with her head stuck in a book.
