    Jeya Maria Jose Valanarasu

    Postdoctoral Scholar, Radiology

    BioDr. Jeya Maria Jose Valanarasu is a postdoctoral scholar working with the Stanford Machine Learning Group and the Center for Artificial Intelligence in Medicine and Imaging (AIMI Center). He leads the AI for Healthcare bootcamp with Dr. Andrew Ng, Dr. Curt Langlotz, and Dr. Nigam Shah which provides Stanford students an opportunity to engage in advanced research at the intersection of AI and healthcare.

    He obtained his Ph.D. and M.S from Johns Hopkins University where he worked on various problems in Computer Vision, Machine Learning, and Healthcare. His research aims to overcome the challenges that arise when translating machine learning models to practical applications for healthcare and engineering sectors. His works have spanned over topics like designing effective deep architectures, model adaptability to changing environments, role of data and annotations, multi-modal learning and taming large models for computer vision and healthcare tasks. He has published over 25 peer-reviewed journal/conference articles at top venues and filed 3 U.S. patents. He has been awarded Amazon Research Fellowship 2022, Best Student Paper Awards at ICRA 2022, CVIP 2019, MICCAI Young Scientist Impact Award Finalist 2022, and the NIH MICCAI Award 2022. He has also served as a reviewer for multiple journals and conferences.

  • Alfredo M. Valencia

    Alfredo M. Valencia

    Postdoctoral Scholar, Psychiatry

    BioFreddy Valencia is a Stanford Science Fellow and Ford Foundation Postdoctoral Scholar at Stanford University. Informed by human genetics and by combining biochemical, structural biology, and functional genomics investigative techniques, his work aims to uncover the molecular basis of human disorders and disease. His current research at Stanford University aims to investigate and characterize chromatin regulatory processes in human brain development and neurodevelopmental disorders.

  • Praveesh Valissery

    Praveesh Valissery

    Postdoctoral Scholar, Infectious Diseases

    BioPraveesh was raised in Chennai, India and studied Biotechnology at the Loyola College while minoring in English Literature. He received his Ph.D. from the Jawaharlal Nehru University (New Delhi, India). He has experience in organic chemical synthesis and molecular biology. With Prof. Suman Kumar Dhar, he studied the cell cycle of the malaria parasite (Plasmodium falciparum) and worked on the optimization of water-soluble Artemisinin nanopreparations in the mouse model of malaria (Plasmodium berghei). His PhD thesis concerned “The design, discovery and improvement of novel and existing antimalarial compounds”. He helped in the synthesis and characterization of a novel class of hybrid antimalarial drug, CQ-CFX.

    In the Egan lab, Praveesh is interested in exploring essential protein-protein interactions taking place at the interface between the malaria parasite and the red blood cell at key moments during invasion. His research involves the use of genome editing tools, including lentiviral and adenoviral vectors to modify hematopoietic stem cells and generate genetically modified red blood cells by ex vivo erythropoiesis.

    In the long term, he hopes to

    1. acquire enough skill to study and develop antimalarial vaccine antigens and improve existing vaccine formulations.

    2. employ a reverse genetics approach to understand mechanisms that facilitate parasite invasion using genetically modified red blood cells.
