    Loza Tadesse

    Ph.D. Student in Bioengineering, admitted Autumn 2016

    BioLoza Tadesse is a PhD candidate in Bioengineering at Stanford University under the supervision of Prof. Jennifer Dionne. Her research develops a rapid, all-optical and label free bacterial diagnostic and antibiotic susceptibility testing system that aims to avoid the time consuming culturing step in gold standard methods. Prior to coming to Stanford, she was medical student at St. Paul Hospital Millennium Medical College in Ethiopia, where she had firsthand experience of the gravity of challenges patients and physicians face in resource limited clinical settings leading her to develop a strong interest in engineering point-of-care medical devices. She has obtained her B.A. degree in Chemistry from Minnesota State University Moorhead and her master’s degree in Bioengineering from Stanford University. Loza is a recipient of several awards including the Stanford EDGE, Agilent and DARE fellowships, the 2019 Biomedical Engineering Society (BMES) career development award and the 2020 BIOX best poster presentation award. She is elected chair of the 2022 Gordon Research Seminar (GRS) on Plasmonics and Nanophotonics and co-founder of SciFro Summer School Program, currently a finalist for the Gates Foundation Grand Challenges call to action, on an effort aiming at inspiring local Ethiopian college students to develop point-of-care medical devices. She was a researcher at IBM Almaden research center and Los Alamos National Labs on several projects including, a patented works using bacteria for battery material design.

  • Longzhi Tan

    Longzhi Tan

    Postdoctoral Research Fellow, Bioengineering

    BioOriginally from Wuhan, China, Tan received his bachelor’s degree in Physics with a minor in Biology from Massachusetts Institute of Technology in 2012, after transferring from Peking University. He worked on bacterial evolution with Jeff Gore, and human evolution with Pardis Sabeti. Tan earned his PhD in Systems Biology from Harvard University in 2018. He worked with Xiaoliang Sunney Xie to develop new methods for single-cell genomics. He uncovered the 3D structure of the human genome in a single cell, and revealed unique chromosome organization in the mouse eye and nose. He also attended the Neurobiology summer course at the Marine Biological Laboratory in 2014, and worked with Ibrahim Cisse at MIT in 2019. Tan is currently a postdoctoral scholar in Karl Deisseroth’s lab at Stanford University, studying single-cell 3D genome changes and spatial transcriptome changes in normal behaviors and psychiatric disorders. Outside of the lab, he enjoys designing holiday cards, t-shirts, and music videos, and is a scientific illustrator.

  • Joseph D. Towles

    Joseph D. Towles


    BioJoseph Towles is a Lecturer jointly appointed in the Mechanical Engineering and Bioengineering Departments at Stanford University. Joe’s teaching interests are in the areas of solid mechanics, neuromuscular biomechanics, dynamical systems and control, and engineering design. His scholarship interest is in the area of engineering education. Specifically, Joe's engineering education activities include student-centric course and curricular development; assessment of student learning & engagement; and innovation in approaches to enhance student learning.

    A Mechanical Engineer by training, Joe earned his BS degree in Mechanical Engineering from the University of Maryland Baltimore County and his MS and PhD degrees both in Mechanical Engineering from Stanford University (1996-2003). Following graduate school, Joe was a research post-doctoral fellow and subsequently a research scientist and then a research assistant professor in neuromuscular biomechanics in the Sensory Motor Performance Program at the Rehabilitation Institute of Chicago and in the Physical Medicine and Rehabilitation Department at Northwestern University (2003-2012). Additionally, Joe was a research health scientist for the Rehabilitation R&D Service in the Department of Veterans Affairs (Hines, IL) during that time and later a scientist in the neuromuscular biomechanics lab in the Mechanical Engineering Department at the University of Wisconsin-Madison (2012-2014). At the time, Joe led projects that addressed the broad question of how to restore hand function (ability to grasp objects) following cervical spinal cord injury and hemiparetic stroke using experimental and computational techniques in biomechanics. As a complement to teaching within the undergraduate and graduate curricula in Biomedical Engineering at the University of Wisconsin-Madison (2014-2018), and now teaching broadly within the undergraduate curricula of Mechanical Engineering and Bioengineering at Stanford, Joe's current scholarship interest has shifted to engineering education.
