Instrument Scientist for JUICE/JENI (designed instrument)

Instrument Scientist for RBSPICE

Instrument Scientist for SPP EPI_Lo (designed instrument)

Instrument Scientist for the Cassini MIMI instrument for 20 years.

Principal Investigator for the Cassini MIMI Instrument

Designed several new instruments, one of which (the hockey puck) is the primary sensor for energetic ion composition on two flight missions (MESSENGER-EPS and New Horizons-PEPSSI), and three upcoming missions (MMS-EPD, Juno-JEDI, and RBSP RB-SPICE). Another (EPI-Lo) has been delivered for flight on Solar probe Plus.

Designed three ENA imagers, one for IMAGE (HENA), oneĀ for Cassini (INCA), one for JUICE (JENI)

Developed a new ENA imager design for increased performance and better background rejection on future missions, now in Phase D for JUICE.

Developed a new ion composition design, for both composition and angular distributions on 3-axis stabilized spacecraft.

Published in Earth magnetospheric, solar wind, outer planets magnetospheric, and heliospheric physics.
