Topic: Towards in-vivo, non-invasive, label-free, real-time 3D histological imaging via 3D quantitative phase contrast Speaker: Dr. Francisco Robles, Associate Professor Wallace H. Coulter Department of Biomedical Engineering Georgia Tech and Emory University Atlanta, GA Zoom Conference Link: https://umassd.zoom.us/j/96205425369 Meeting ID: 962 0542 5369 Passcode: 337041 Abstract: Quantitative phase imaging (QPI) and refractive index (RI) tomography enable label-free measurements of biological samples with exquisite subcellular contrast and nanometer-scale sensitivity, providing unprecedented access to important histological and biophysical information of cells and tissues non-invasively. However, conventional QPI and RI tomography methods are restricted to thin samples due to their reliance on a transmission-based optical geometry, which hinders their overall clinical utility, particularly for in vivo applications. To overcome this important challenge, my lab has recently developed a technology called quantitative oblique back-illumination microscopy (qOBM), which provides the same level of quantitative cellular and subcellular histological and biophysical information but with epi-illumination. Thus, qOBM can be applied to image large tissues, non-invasively and in vivo, enabling many new applications that were previously out of reach of conventional phase imaging technologies. In this presentation I will discuss the theory and inner workings of qOBM, along with my lab's efforts to apply this technology to novel biomedical and clinical applications, including imaging organoids and assessing brain tumor margins in vivo. Biography: Dr. Robles is an Associate Professor at the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University. He earned his PhD in Medical Physics from Duke University, followed by a postdoctoral fellowship at Duke in the department of Chemistry. His lab at Georgia Tech and Emory University focuses on developing and advancing label-free optical imaging and spectroscopy technologies to help improve our understanding of biological processes and our ability to identify disease. The Seminars is open to the public free of charge. *For further information, please contact Dr. Ana Doblas via email at adoblas@umassd.edu.

The third annual Run for Veterans 5K will be on Veteran's Day weekend, Saturday, November 9, 2024. All proceeds will go towards supporting UMass Dartmouth student veterans. Registration is open now until 12pm on Nov. 8. All runners will get a runner's packet which will include a custom bib, an event t-shirt and a special gift. The run will take place on the UMass Dartmouth campus. Check in will open at 8am the day of the race and the run itself will start at 9am. All runners will receive a timing chip to record accurate start/finish times and medals will be awarded to the top three runners in each age category (12 and under, 13-17, 18-35, 36-50, 51-65, 65+). Snacks will be provided after the run for all participants to recharge.

Topic: Imaging the cellular effects of directed energy using advanced microscopy Speaker: Dr. Zachary A. Steelman, Research Biomedical Engineer 711th Human Performance Wing Air Force Research Laboratory (AFRL) Joint Base San Antonio, Fort Sam Houston, TX. Location: Lester W. Cory Conference Room Science & Engineering Building (SENG), Room 213A Zoom Conference Link: https://umassd.zoom.us/j/97175731135 Meeting ID: 971 7573 1135 Passcode: 806238 Abstract: Directed energy - including lasers, pulsed electric fields, free-field microwaves, and radiofrequency radiation's induce unique biological effects which can be difficult to quantify. My talk will present an overview of advanced optical imaging systems, developed within the Bioeffects Division of the Air Force Research Laboratory (AFRL), which help to visualize and quantify the impacts of directed energy exposure at the cellular level. Imaging techniques include quantitative phase imaging (QPI), Brillouin spectroscopy, custom 3D-printed fluorescence microscopy, and streak- and strobe-photography for ultrafast imaging. System design and applications for understanding mechanisms of directed energy-induced cellular damage are discussed. Biography: Dr. Zachary A. Steelman is a Research Biomedical Engineer at the 711th Human Performance Wing, Air Force Research Laboratory (AFRL), Joint Base San Antonio, Fort Sam Houston, TX. Dr. Steelman completed his PhD in Biomedical Engineering, as well as a Master's Degree in Electrical and Computer Engineering, at Duke University in 2020. After a brief postdoc with the National Research Council (NRC), Dr. Steelman joined AFRL in 2022. Dr. Steelman's work focuses on designing advanced optical imaging systems to characterize the biological effects of directed energy exposure. He is the author of 30 scientific journal articles and has been recognized with numerous national and international awards. The Seminar is open to the public free of charge. *For further information, please contact Dr. Ana Doblas via email at adoblas@umassd.edu.
