Dr. Hakkila's research interests include gamma-ray bursts, peculiar abundance stars, and multi-wavelength observational astronomy.

Dr. Hakkila studies gamma-ray bursts (GRBs), which are the most energetic explosions in the universe. Dr. Hakkila's interests have been primarily in the study of GRB prompt emission, which is the initial onslaught of high energy emission accompanying these violent events. Dr. Hakkila has been active in the study of GRB classes, statistical analyses of GRB prompt data, selection biases due to observation and instrumental effects, and the study of the constituent pulses that comprise GRB prompt emission. He is currently analyzing data from the Burst and Transient Source Experiment (BATSE), the Swift satellite, and the Fermi satellite. His work has been supported by grants from the National Aeronautics and Space Administration (NASA), the National Science Foundation (NSF), and the National Research Council (NRC)

Dr. Hakkila also studies barium stars, metallic-lined A (Am) stars, stellar spatial distributions and luminosities, and infrared/visual photometry.
