Rafay Ahmed received his PhD from City University of Hong Kong in 2019. There he diagnosed the healing of calvarial defects by assessing the molecular and elemental changes using Raman spectroscopy, X-Ray fluorescence spectroscopy, optical profiling and microscopies. Additionally, he developed the Laser Induced Breakdown Spectroscopy system in his lab that was used for several elemental studies including bones, teeth, thyroid, Red blood cells etc. Currently, Rafay is working as postdoctoral research fellow in Dr. Nyman’s lab on the development of Spatially Offset Raman Spectroscopy to translate it for clinical assessment of bone matrix quality; to diagnose the reasons of fragility fractures in type 2 diabetes; fatigue testing of cortical bones using single edge notch bend specimen and assessing the ability of Raman spectroscopy to predict mechanical properties of human bone.

Erik is a 4th-year cancer biology graduate student in the Rhoades lab. He came to Vanderbilt in 2016 after completing his bachelor’s in biology (2014) and master’s in molecular science and nanotechnology (2016) at Louisiana Tech University. Erik’s master’s thesis focused on transcriptional control of bone marrow mesenchymal stem cell differentiation, which corresponded well to the research in the Rhoades lab. His current research is focused on solidifying the link between Gli2 and PTHrP in tumor-induced bone disease while identifying how this interaction facilitates the development of osteosarcoma.

I received my PhD from Institute of Genomics and Integrative Biology (IGIB) in New Delhi, India in 2020. My thesis work was focused on lipid metabolism in tuberculosis. I was trying to find out how Mtb rewires its physiology to adapt to lipid rich niche which it faces in human granuloma post infection. I joined Beth’s lab in January 2021 as a post-doctoral researcher. Currently, I am studying the importance of lipid metabolism in the maintenance of bone homeostasis.
