MEET THE PI

Dr. Alejandro Bertolet, PhD

Dr. Bertolet is an Assistant Professor of Radiation Oncology at Harvard Medical School, the Director of the Radiopharmaceutical Dosimetry Program at the Mass General Hospital, and a faculty on the Division of Physics at MGH Radiation Oncology. He is a medical physicist certified for clinical duties in Spain, and has expertise in mathematical and computational modeling, Monte Carlo simulations and the radiobiology of radiation therapy.

Alejandro completed his PhD studies at the Universidad de Sevilla (Spain), working as a scholar in the University of Pennsylvania, and since then has been a member of MGH, where he has obtained multiple NIH-funded projects. He is a member of the SNMMI MIRD Committee, the co-director of the RPT track for the AAPM annual meeting, and the current John D. Boice awardee by the NCRP.

Our current Lab Members

Carlos Huesa-Berral
Postdoctoral Fellow

He builds computer and benchtop models that track how radioactive microspheres move through blood vessels and deposit dose. His goal: turn raw physics into treatment maps doctors can trust.

Victor V. Onecha
Postdoctoral Fellow

He writes the heavy-duty code that powers our microdosimetry and imaging. From GPU-accelerated SPECT recon to DNA repair time-lapse models, he turns billions of particle track into fast answers about risk and benefit.

Debangana Mukhopadhyay
Postdoctoral Fellow

She leads AMBER, an agent-based model that simulates whole populations of cancer and normal cells reacting to radiation. She tests how timing, fractionation, and micro-environment cues tilt the balance between cure and ciomoplication.

José Antonio López-Valverde
Postdoctoral Fellow

He explores how tiny helpers (nano-particles, radio-activatable pro-drugs, DNA-damage foci detectors) can make radiation hit harder or spare healthy tissue. He mixes wet-lab biology with image analysis software to see which tricks actually work in cells.

Mislav Bobić
HMPRP Resident

He develops patient-specific liver vasculature to see blood-dose studies that track radiation exposure to circulating cells. He also quantifies tracers like 64Cu-Macrin to show where immune cells cluster and how much the patient organs receive.

Kebert Joseph
Research Assistant

He mines Y-90 liver cancer cases, linking dose maps and other patient-specific features to real world tumor control and side effects. His analysis shape ho we adjust prescriptions for each patient.

Daniel Puerta
Ph.D. Student

He builds the ChronoRepair digital-twin of DNA-damage repair and uses of microdosimetry data to compare how different radiation qualities break tumor cells.

Cecilia Nova Wijaya
M.Sc. Student

She extends the Microdsoimetric Gamma Model (MGM) so that a single track-structure run spits out a fast but-accurate RBE estimate, trimming days of compute from radiobiology studies.

Bobby Dawson
Ph.D. Student

He designs flow phantoms and Monte Carlo maps that predict where Y-90 microsphere lodge in each patient’s liver, guiding dose prescriptions and catheter placement.

Maëlyne Bennasar
M.Sc. Student

She uses AMBER to produce synthetic images of virtual tumors, which allows us to compare how the tumor is simulated to evolve with real data.

Alexis Parker
AAPM DREAM Student

She quantifies microsphere clustering in Oncopig liver tumors: histology, PET scans, and fluid-dynamics data that ground-truth our radioembolization models.

Faria Tavacoli
CURE Student

She curates the DNA-damage literature and benchmarks ChronoRepair against published survival curves, keeping the code honest and the datasets reproducible.

Andrea Vidal
M.Sc. Student

She studies the mechanisms of action of radiosensitizing nanoparticles in ovarian cancer, and helps developing predictive models to optimize this therapeutic strategy.

Felix Huyghe
Junior Orsi Fellow

He works on physiology-based pharmacokinetic modeling to be applied to dosimetry for radiopharmaceutical therapy when imaging availability is limited.

Caleb Beroukhim
High-school Student

He is working on mathematical models for drug transport across membranes, with special focus on the blood-brain barrier and radiopharmaceuticals for glioblastoma therapy.
