Background:
I lead Alicanto Labs, a small technology company that transfers adademic research on strategic mine planning. We develop a large-scale production scheduling software for Open Pit and Underground Mining that we call Alicanto Solver. We have recently started working on stochastic and sustainable mine planning. Alicanto Solver currently powers the Deswik.GO software, used by many of the world's largest mining companies. We have also used Alicanto Solver in a number consulting projects requiring customized planning solution.
I hold a PhD in Industrial Engineering from the School of Industrial and Systems Engineering (ISYE) of Georgia Tech. I have an undergraduate degree in Mathematical Engineering which I obtained from the School of Engineering of Universidad de Chile. I formerly worked at the Business / Administration School at Pontificia Universidad Catolica de Chile. I occasionnaly teach courses related to Operations Management and conduct research, both theoretical and applied, on Mathematical Programming and Operations Research. Some of my research interests include: scheduling operations for forestry and mining, the traveling salesman problem, and mixed integer programming methodologies.
