Joel Barnes joined the HALO Group in 2010 and his impact was felt immediately and progressively throughout his 10-year tenure. His diverse skill set served the HALO group well as he routinely solved problems related to analyses, data management, and information technology while providing exceptional service, assistance, and quiet leadership in all areas. He is an extraordinary polymath who in addition to providing expert input on all aspects of research infrastructure, management and analysis, also ran to/from work every day (12 km round-trip) and played chess on-line during his mental “breaks”. He will be missed and will be very difficult to replace. Everyone at HALO wishes him the very best and expects to see him at all HALO social events as a valued alumnus.
