Dr Hoffman grew up in Buffalo, New York. He was turned on to astronomy by his piano teacher during middle school and went on to graduate from the Nichols School. As an undergraduate at Colgate University in physics and astronomy, his research thesis was on ultrafast laser and terahertz instrumentation. Subsequent graduate study in astrophysics at Penn State involved pulsar research at Arecibo in Puerto Rico and at IRAM in Spain. In moving to the University of New Mexico, Dr Hoffman completed a Masters in physics in a pulsed-laser lab and a dissertation as a Grote Reber Fellow in residence at the National Radio Astronomy Observatory on interferometric imaging of interstellar masers using MERLIN in England, the Very Large Array, and the Very Long Baseline Array.
An experimental physicist, Dr Hoffman worked in industry prototyping linear particle accelerators and as a laser spectroscopist for government customers before returning to academia. In terms of teaching prior to coming to Wittenberg, Dr Hoffman was a lecturer at the University of New Mexico, New Mexico Tech, and the University of New Hampshire, and faculty at St. Paul's School in Concord, New Hampshire.
