Collins Lartey PhD
Collins Lartey is a PhD student in Mathematical and Computational Physics, where he is working broadly on computational astrophysics with special focus on planetesimal formation in multi-ringed protoplanetary disks using computational and numerical techniques. He is currently a visiting PhD researcher at the University of L'Aquila in Italy. He holds a MPhil in Mathematical and Computational Physics and a BSc in Physics, both from the KNUST, and a MSc in Mathematical Engineering from the University of L'Aquila, Italy. He supports the MCP programmes that train students and early-career researchers in applied mathematics, astrophysics and related fields.
