Fatouma Toure, MD, PhD
As a Nephrologist, my postdoctoral training in the Diabetes Research Program was the perfect time for me to discover the fundamental aspect of RAGE implication in the diseases I was seeing in patients. I was lucky to be part of a project exploring the numerous and critical signaling pathways induced by RAGE activation. The focus of my attention was the interaction of RAGE with molecules from the formin family and the implication of this interaction on RAGE-induced redox signaling. The studies were made in vivo and in vitro, and they highlighted key roles for formins in RAGE-mediated effects. I was also associated with projects studying the progression of diabetic glomerulosclerosis and the role of RAGE in this phenomenon.
I am currently working as an Assistant Professor/Hospital Practitioner at Hospital University of Reims and Research Unit CNRS UMR 6237, France. – Fatouma Toure, MD, PhD

Srinivasan Vedantham, PhD
As a postdoctoral fellow in the Diabetes Research Program my main research focus was to understand the role of Aldose Reductase (AR) in causing early atherosclerosis diabetes and to delineate the mechanisms by which they do so. Important findings have been made in understanding how polyol pathway affects NAD+ synthesis and sirtuin activity in early atherosclerotic events.
I am currently working as a scientist at the Madras Diabetes Research Foundation, Chennai, India, leading a program in Growth & Development in Metabolism. My present research focus is on understanding how maternal blood and food-derived Advanced Glycation End-Products (AGEs) predispose to diabetes and other chronic metabolic diseases in infants and young children. Additionally I am also interested in understanding developmental programming of obesity and metabolic syndrome during the life course.

Zhou Chen, MD, PhD
As a postdoc, I was lucky to participate in an aging project. The project involved the use of primary cultured endothelial cells isolated from young and aged rats for vitro studies. Young and aged wild type and RAGE knockout mice were also used for in vivo studies. As a member of the Diabetes Research Program, we found that RAGE modulates expression of proinflammatory and procoagulant genes in response to aging and hypoxia stresses.
My new position is Associate Professor of Pharmacology at Fujian Medical University in China. In addition to my lecturing duties, I will continue to focus on Geriatrics and the diseases related to aging.

Lingjie Wang, MD, PhD
As a cardiologist, the postdoctoral fellow training in the Diabetes Research Program was a crucial step in my academic career. My primary project was to address the mechanisms by which RAGE blockade protects hearts from high fat diet induced functional and metabolic changes. Specifically, it revealed the impact of RAGE blockade on cardiac mitochondrial biogenesis in HFD-induced obesity mice or high fatty acid treated cardiomyocytes.
I was lucky to be part of a project establishing the impact of aldose reductase pathway on mitochondrial function and mitochondrial biogenesis in acute and chronic diabetic hearts. The aim was to investigate the potential mechanisms by which aging and diabetes increase vulnerability of hearts to ischemia-reperfusion injury. I also participated in studies that resulted in demonstrating cardio-protection afforded by the carbon monoxide form of PEGylated hemoglobin (SANGUINATE™) in diabetic and non-diabetic mice models of myocardial infarction.
I am currently working as a physician of Cardiology at Ruijin Hospital of Shanghai Jiao Tong University School of Medicine, Shanghai, P.R. China.

Judyta Juranek, DVM, PhD
As a postdoctoral fellow in the Diabetes Research Program, I worked on deciphering the role of the Receptor for Advanced Glycation End-Products (RAGE) and its most prominent ligands in the pathogenesis of diabetic peripheral neuropathy. Studies showed that in normoglycemia peripheral neuronal RAGE contributes to effective axonal regeneration prompted by acute crush injury; while in diabetes, intact peripheral nerve studies showed that RAGE signaling is a deteriorating factor.
In the present study I hypothesized that in diabetes, peripheral nervous system RAGE contributes to progressive neuropathy and that upon superimposed acute injury, RAGE-dependent neuronal dysfunction would worsen, thereby attenuating neurite outgrowth and further suppressing effective axonal regeneration and re-innervation of target tissues. The findings of the study, published in Diabetes (Juranek et al, 2013) provide evidence that RAGE suppresses effective axonal regeneration in diabetic peripheral nerve after acute injury.
Throughout this project, I have had the opportunity to advance my laboratory skills as well as evolve as a mentor to undergraduate students. In addition to my laboratory and mentoring tasks I have also acted as a head of a microscopy unit in my laboratory and have been responsible for training laboratory members in microscopy techniques, image capturing and signal quantification.
My future plans include continuing my efforts to further deepen my knowledge of the pathogenesis of neurodegenerative disorders. I will investigate new treatments by actively engaging in collaboration with my fellow researchers and aim to create joint multilevel projects.

Vivek Rai, PhD
Dr. Rai was born in Allahabad, India and received his Ph.D. from Jawaharlal Nehru University (JNU), New Delhi, India. He joined Dr. Ann Marie Schmidt's laboratory as a Postdoctoral Research Scientist in 2008 at Columbia University Medical Center and later at the Diabetes Research Program, NYU Langone Medical Center. His research focused on two areas: the study of the RAGE ligands family of molecules and how they regulate RAGE signaling and the analysis of the mechanisms by which RAGE mediates diabetic complications.
Dr. Rai is currently working as a Principal Investigator at Institute of Life Sciences (ILS), Bhubaneswar, India; a leading institute specializing in infectious diseases. He is the recipient of two prestigious 2012-13 awards: the Ramanujan award and the Ramalingaswami Fellowship which is primarily given to selected Indian scientists working overseas. His present research focus is on understanding the molecular mechanisms and signaling events associated with vascular immunology in pathogenesis.

Mariane Abdillahi, PhD
During my research studies at the Diabetes Research Program, I investigated the signal transduction mechanisms by which the aldose reductase (AR) pathway contributes to the vulnerability of the myocardium to ischemic challenge. I worked to elucidate whether AR pathway mediated ischemia-reperfusion (I/R) injury is linked to changes in GSK3 beta phosphorylation and to autophagy.
Studies have provided contrasting conclusions on whether induction of autophagy is protective during I/R. Therefore, my goal was to determine whether increased flux via AR influences autophagy induction during I/R injury. These research efforts were published in the American Journal of Physiology: Heart and Circulatory Physiology and shred insight into the mechanisms via which AR modulates changes in GSK3 beta phosphorylation and highlighted potential therapeutic targets for myocardial infarction.
I am currently continuing my research training at Columbia University. I am working to understand the role of triglycerides in metabolism and the pathogenesis of diabetic vascular disease. My long term goal is to employ my scientific training and communication skills to pursue a career in science policy with the aim of understanding how scientific research drives recommendations and implementation for public policies.

Devi Thiagarajan, PhD
As a postdoctoral fellow in the Diabetes Research Program, my main focus was to understand the role of Aldose Reductase (AR) in mediating secondary complications in the heart and to underpinning the mechanisms related to it. My contribution was in delineating the epigenetic mechanisms associated with increased polyol pathway and how it results in ectopic lipid accumulation in the heart.
I am currently working as a research associate at University of Southern California, Los Angeles. My present work involves understanding the epigenetic events leading to increased susceptibility of the aging population to cancer. I am also interested in understanding the epigenetic mechanisms related to aging.
