Mariana Acquarone was born and raised in Rio de Janeiro Brazil. She received her PhD degree in Morphological Science - Neuroscience at Federal University of Rio de Janeiro, focusing on stem cell therapy for Parkinson`s disease. She worked at the Federal University of Rio de Janeiro and Pablo Olavide University (Spain) where she studied embryonic and induced pluripotent stem cells (iPSCs) as alternative sources for cell transplant in Parkinson and other neurodegenerative diseases. In 2022, she joined Dr. Karch's Lab to start working on microglia leveraging iPSCs and the generation of iPSCs-derived microglia and neurons to model the brain during neurodegenerative pathologies. Mariana is a dog lover and enjoys spending time with her loved ones, gardening, and dancing. 

Christian Andino received his B.S. in Cell & Molecular Biology from Ana G. Mendez University (Puerto Rico). Christian joined the Karch lab as a Postbaccalaureate in the summer of 2022 and is broadly interested in the functionality and maintenance of stem cells to better understand how diseases and conditions develop. In his free time, he likes to go to the gym, try a new restaurant, and explore green areas.

Roesha Andre received her B.A. from Dartmouth College and her M.Sc from University of Michigan where she studied and monitored amyloid formation using fluorescence techniques. While completing her Masters, she gained expertise in molecular, cellular, and developmental biology, particularly with a focus on aging interventions and neurodegeneration. In the Karch Lab she will work to advance efforts around the mechanisms and characterizations of the relationship between MS4A genes, soluble TREM2 (sTREM2) and microglial function in Alzheimer’s disease. In her free time she enjoys cooking, exploring nature with her dog, and dancing.

Bhagyashri Burgute completed her Ph.D from University of Cologne, Germany. During her scientific career, she has gained expertise in protein biochemistry, cell biology, molecular biology, and RNA biology. In the Karch Lab her research is focused on aging dependent neurodegeneration. Bhagyashri is interested in inducing aging phenotype in iPSC derived cellular models of AD to assess its impact on disease progression.

In her free time, Bhagyashri enjoys spending time with her family, outdoor activities, and music.

Arthur Li is a graduate researcher with a BS in BME and CS, and currently working on his MS in BME. His major interests include biomedical image processing, machine learning, cardiac electrophysiology, and bioinformatics. Arthur is currently working on the cellular deconvolution project concentrating on improving microglia results.

Sidhartha Mahali received his PhD at the Center for DNA Fingerprinting & Diagnostics, Hyderabad, India. His dissertation was focused on understanding Advanced Glycation End product (AGE)-mediated cellular responses. As a post-doctoral fellow at KU Leuven, Belgium, he studied the complex interplay of kinases and phosphatases that regulates microtubule-associated proteins. His current position in the Karch lab leverages his expertise in cell biology, microscopy and training in stem cell models of neurodegeneration to develop his research career in the field of neuroscience. 

Sidhartha’s current research focuses on the lysosomal machinery in iPSC-derived neural cells with FTD mutations. His findings suggest that mutations in MAPT, PSEN1 and PSEN2 are sufficient to cause impaired lysosome function and tau accumulation, which may drive disease pathogenesis.  

Apart from being a dedicated researcher, he is an avid reader, amateur birdwatcher, nature photographer and a practitioner of thoughtless meditation.  

Prior to working in Dr. Karch's lab, Rita worked in the GEiC (Department of Genetics, WUSTL) developing tools and protocols for iPSCs reprogramming, production, differentiations and genome editing.  The devolpment of iPSCs and genome edting techniques have been of keen interest to her research and the study of neurodegenerative disease. Previously, Ms. Martinez worked in the biotech industry utilizing human iPSCs which were then used to model ALS and Alzeheimers diseases. 

Matthew is a senior PhD candidate in the Molecular Cell Biology program, his research focuses on the role of PLD3 in driving Alzheimer disease pathogenesis.

Ani performs various molecular biology techniques in the lab, and primarily oversees the maintenance, expansion, and characterization of iPSC lines. Ani received his Bachelors of Science from University of Illinois at Urbana-Champaign. Currently, he also works on a project aimed at elucidating the role of AGFG2 in various forms of familial Alzheimer's Disease.
