BME 7900 Seminar - Scott Manalis, PhD

Friday, November 1, 2019 at 2:30pm to 3:30pm

Weill Hall, 226

We welcome our next guest speaker, Dr. Scott Manalis from the Massachusetts Institute of Technology. He is the Andrew and Erna Viterbi Professor of Biological Engineering and also an intramural faculty member of the Koch Institute for Integrative Cancer Research.

Dynamic and high-precision biophysical measurements of single cells

Abstract: Dr. Manalis will present two projects where novel approaches are used to monitor phenotypic properties of single cells. The first focuses on single-cell mechanics, which are critical in processes such as tissue development and cancer invasion. However, monitoring mechanical changes of the same cell with high-temporal resolution remains challenging primarily due to invasiveness of the measurement. He will show that scattered acoustic fields from a living cell measured inside a fluid-filled vibrating microchannel is dependent on the cortex thickness and elastic modulus. By monitoring acoustic scattering with a temporal resolution of <1 min continuously throughout multiple generations in mammalian cells, they observe mechanical dynamics during mitosis on timescales that have previously been difficult to access. The second project focuses on circulating tumor cells (CTCs), which play a fundamental role in cancer progression. However, in mice, limited blood volume and the rarity of CTCs preclude longitudinal, in-depth studies of these cells using existing liquid biopsy techniques. To address this, they have devised a method for collecting CTCs from an un-anesthetized mouse longitudinally – spanning multiple days or weeks – to study acute perturbations (e.g. drug treatment) or potentially long-term phenotypes (e.g. tumor progression) within the same mouse. He will show that their microfluidic-based approach eliminates confounding biases driven by inter-mouse heterogeneity that can occur when CTCs are collected across different mice for single-cell RNA-Seq measurements.

Bio: Scott Manalis is the Andrew and Erna Viterbi Professor of Biological Engineering and a member of the Koch Institute for Integrative Cancer Research. He has been a faculty member at Massachusetts Institute of Technology since 1999 and prior to that he received his undergraduate and graduate degrees in physics and applied physics at University of California
