Julian Hall

Julian Hall is a Professor in the Department of Mathematics at the University of Edinburgh, specializing in optimization and operational research. He is a key developer of HiGHS, an open-source linear optimization software, and previously developed a solver used in global animal feed formulation and oil reservoir management. His research focuses on enhancing the simplex method for linear programming efficiency. Julian holds a PhD from the University of Dundee under Roger Fletcher after studying at Oxford and working at ICI/AstraZeneca. He has received four best paper awards, including COAP recognitions in 2005, 2013, 2015, and 2018. His work bridges academia and industry, with funding from Google and Huawei. Julian emphasizes applied mathematics’ real-world impact, particularly in agriculture and computational sustainability.

• Education: PhD in Numerical Analysis and Optimization (Dundee), MSc (Dundee), BA (Oxford), King’s School (Macclesfield).
• Research Interests: Linear programming algorithms, parallel computing, optimization in agriculture and environmental systems.

His software HiGHS is deployed in multi-billion-dollar industries, solving problems like optimal animal feed blends and sustainable livestock production. Julian collaborates with industrial partners and mentors PhD students advancing optimization techniques. His recent work includes parallel simplex methods and GPU-accelerated algorithms, reflecting his commitment to scalable computational solutions.
