Darijana Horvat - Research Assistant / Lab Manager
Darijana Horvat received her B.S. in Chemistry from Texas A&M University. During her undergraduate career, she worked with Dr. Coran Watanabe investigating the mode of action and biosynthesis of azinomycin B. She also interned at the Institute Rudjer Boskovic (Division of Organic Chemistry and Biochemistry) in Zagreb, Croatia where she separated enantiomers using HPLC.
After graduation Darijana worked in several labs, studying preeclampsia, hypertension, cancer (cholangiocarcinoma), lymphatics, microbial pathogenesis and immunology. She joined the Geoffroy lab in December 2019 as the Research Assistant/Lab manager. One of her projects is to test the protective and regenerative properties of different test compounds in mice models of spinal cord injury.
In her free time Darijana enjoys playing trivia, board games and billiards with her friends and family. She likes music, live theater performances, movies and TV shows. In her quiet time she loves to read books.
Theresa Sutherland - Post-Doc
Theresa completed a Bachelor of Forensic Biology in Biomedical Science from the University of Technology Sydney (yes, Australia!), with a special interest in DNA profiling and ambition to work in CSI. Then she completed a Bachelor of Science (Honors) in Biomedical Science at UTS where she studied the acute cellular response to SCI in different ages of rats. Theresa then obtained her Ph.D. in Neuroscience at UTS in Dr. Catherine Gorrie lab (University of Technology Sydney) studying injury progression and neuro-inflammation after SCI with a particular focus on the differences between adult and pediatric SCI.
Theresa recently joined our lab to continue working on the themes of age and SCI, looking into older animal this time…She's trying to understand the age-dependent decline in the growth and regenerative potential of axons, with a specific interest in the role of STAT3 and mitochondrial dynamics. The eventual goal of which is to restore regenerative potential to aged axons, and find strategies to enhance axon growth and functional recovery after SCI irrespective of age. She is also involved in different projects aiming at developing tools to accelerate the discovery of molecules controlling axon growth (non-viral CRISPR/Cas9 in vivo targeting, in vivo protein delivery, 3D imaging). In the long term (very long term), she hopes to marry this ongoing work to her interest in pediatric SCI and to get a map/timeline of neuro-inflammation and axon regeneration across all ages to find effective therapeutics for all SCI patients.
Theresa loves to escape into different worlds- Movies, Books, Music, TV- and explore this one (yes, traveling!). Also, she can not stop drinking coffee...
Adel Ghnenis - Post-Doc
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)
Arthur Sefiani ()
Arthur first completed a Bachelors of Science in Neurobiology, Physiology, and Behavior at University of California, Davis where he was involved in studying the relationship between proteasomes and cardiovascular disease and also how attention influences one’s neural analysis of sound. Afterward, he became a lab technician at a forensic laboratory, one of the few places that conduct hair follicle drug testing. He then completed his Masters of Science in Biochemistry and Molecular Medicine at Keck School of Medicine of University of Southern California where he worked on developing several methods to accurately quantify the kinetic rates of RNA binding protein. Arthur is currently a Ph.D. student in the Medical Sciences program in the Department of Neuroscience and Experimental Therapeutics.
He spends all his free time weight lifting or eating, sometimes both.
