The members of the Wellman Center Career Development and Promotions Committee
(Tayyaba Hasan, Brett Bouma, Bobby Redmond, Gary Tearney and Andy Yun) are pleased to
announce the promotion of Arutyun Bagramyan, PhD to the rank of Instructor at Harvard Medical
School effective September 1, 2025.
Dr. Bagramyan completed his PhD study in Physics at Laval University in Canada and joined Dr.
Charles Lin’s Advanced Microscopy Laboratory at the MGH Wellman Center for Photomedicine. In his
short time, he has transformed the research landscape in the laboratory, adding a new translational
focus to a team that has previously focused on basic studies of the hematopoietic system in live mice
using intravital microscopy. Dr. Bagramyan first developed a miniaturized microscope (mOBM) capable
of label-free, phase contrast imaging of individual blood cells in the human microcirculation. Using this
device, he captured stunning videos of leukocyte rolling and adherence on the vascular endothelium -
the first steps of the leukocyte recruitment cascade and a hallmark of inflammation. This work was
published in Scientific Reports (2023), “Miniaturized microscope for non-invasive imaging of leukocyte-
endothelial interaction in human microcirculation".
Dr. Bagramyan demonstrated the ability to detect not just the slow-rolling cells but also fast-flowing
cells in the bloodstream. He validated the developed microscope system in 34 human volunteers and
established the first benchmarks for reliable image-based WBC count measurements. These results
are presented in his second paper, “Towards Non-Invasive White Blood Cell Count in Humans,''
Biomedical Optics Express (2025). In addition, he has a patent application, “System for Stabilized
Noninvasive Imaging of Microvasculature in the Oral Mucosa.”, #WO2023230463A3 (2023), which is in
the international PCT stage.
Dr. Bagramyan is now developing an even more compact version of the device for use on neonates.
Noninvasive blood cell analysis is useful for infants because of their high risk of infection and anemia
from repeated blood sampling. Working in collaboration with Dr. Martha Sola-Visner, Director of
Newborn Medicine Clinical Research Program at Boston Children’s Hospital (BCH), Dr. Bagramyan
has assumed a leadership role on this project, responsible for everything from the development of the
instrument to the submission of the IRB and coordination with the clinical staff at BCH.
Well done Arutyun and we wish you the very best in the coming years and continued success!

The MGH Research Scholars program was launched in 2011 by the hospital and the Research Institute Advisory Council to provide forward-thinking researchers with the unrestricted funding they need to take their work into new and uncharted territories.
Congratulations to Dr. Conor Evans on receiving the 2025 MGH Research Scholars Award!
Congratulations to Vietta for passing her qualifier with flying colors! Vietta is doing her PhD program in Biophysics in the Evans Lab
Dr Tayyaba Hasan PhD was recently awarded the prestigious PAESMEM Award by The White House Office of Science and Technology Policy (OSTP) in concert with the National Science Foundation (NSF). The specific award: Individual category: Presidential Award for Excellence in Science, Mathematics and Engineering Mentoring (PAESMEM). This achievement reflects the significant contributions she has made to the field of mentoring and her contributions in the areas of science, technology, engineering, and mathematics. Dr. Hasan is one of only 12 individual recipients for this year in the nation.
Established by Congress in 1995, this award honors the hard work and dedication mentors exhibit in broadening participation in STEM pathways. PAESMEM specifically honors individuals and organizations that have demonstrated excellence in mentoring individuals from groups that are underrepresented in STEM education and the workforce. Over the course of Dr. Hasan’s career, she has graciously mentored over 300 candidates who are successfully making huge impacts in their fields.
