    "Seeing the Unseen Using Molecular Fingerprints"

    ABSTRACT:
    Spectrochemical imaging, using intrinsic fingerprint spectroscopic signals from molecules as a contrast mechanism, opens a new window for understanding life at the molecular level and also enables molecule-based precision diagnosis of diseases. Yet, the intrinsic spectroscopic signal, especially the vibrational signals from chemical bonds, is weaker than the fluorescence signal from a dye by many orders of magnitude. Detecting such weak signal from a tight focus (i.e., a small volume of ~1 femtoliter) under a microscope is extremely challenging and was considered nearly impossible. Ji-Xin Cheng devoted his career to overcoming such daunting barrier through developing advanced chemical microscopes over the past 25 years. In this lecture, Cheng will tell his journey of serendipity-driven innovation, scientific discovery, clinical translation, and entrepreneurship in the growing field of chemical imaging, with a focus on the invention of vibrational photothermal microscopy.

    BIO:

    Ji-Xin Cheng attended University of Science and Technology of China (USTC) from 1989 to 1994. From 1994 to 1998, he carried out his PhD study on bond-selective chemistry at USTC. As a graduate student, he worked as a research assistant at Universite Paris-sud (France) on vibrational spectroscopy and the Hong Kong University of Science and Technology (HKUST) on quantum dynamics theory. After postdoctoral training on ultrafast spectroscopy in 1999 at HKUST, he joined Sunney Xie’s group at Harvard University as a postdoc from 2000 to 2003, where he focused on the development of CARS microscopy that allows high-speed vibrational imaging. Cheng joined Purdue University in 2003 as Assistant Professor in Weldon School of Biomedical Engineering and Department of Chemistry, promoted to Associate Professor in 2009 and Full Professor in 2013. He joined Boston University as the Inaugural Theodore Moustakas Chair Professor in Photonics and Optoelectronics in summer 2017. Cheng devoted his research career to chasing a far-reaching goal – harnessing intrinsic molecular signatures for label-free imaging, molecule-based diagnosis, and drug-free treatment.

    Scholarship: Professor Cheng is authored in 350 peer-reviewed publications with an h-index of 105 (Google Scholar), holder of >40 patents. Cheng’s research has been supported by >50 grants, ~50 million ($) funding, from federal agencies including NIH, NSF, DoD, DoE and private foundations including Chan-Zuckerburg Initiative and Keck Foundation.

    Entrepreneurship: In 2014, Professor Cheng co-founded Vibronix Inc which is devoted to vibration-based imaging technologies and medical device innovations. In 2019, Professor Cheng co-founded Pulsethera aiming to kill superbugs by photolysis of intrinsic chromophores. Professor Cheng is the Scientific Advisor of Photothermal Spectroscopy Corp in Santa Barbara and of Axorus in Paris. Chemical microscopes based on his innovations (e.g., mIRage by Photothermal Spec Corp) are installed and used in many countries worldwide.
