• Timing detectors
• Photon detectors for UV, visible and IR photons (solid-state) (PIN diodes, APDs, Si-PMTs, G-APDs, CCDs, EBCCDs, EMCCDs etc)
• Pixelated detectors and associated VLSI electronics
• Instrumentation and methods for time-of-flight (TOF) spectroscopy

We present a 4 x 4 array of digital silicon photomultipliers (D-SiPMs) capable of timestamping up to 48 photons per D-SiPM and we show the advantage of generating multiple timestamps in the context of positron emission tomography (PET). The D-SiPMs have a pitch of 800 mu m and comprise 416 pixels each; the timing resolution achieved by the SiPMs is 179 ps FWHM, while each pixel has a fill factor of up to 57 % and a single-photon timing resolution of 114 ps.
