Applications are invited for one or more postdoctoral positions to carry out research in the development of novel optimization methodologies for solving hard combinatorial problems arising in real-world applications. The positions may be based at either the University of Waterloo (http://www.uwaterloo.ca) or the University of Guelph (http://www.uoguelph.ca). The lead investigators are Professors Miguel Anjos (Waterloo, Management Sciences), Anthony Vannelli (Guelph, Engineering), Stephen Vavasis (Waterloo, Combinatorics & Optimization), and Henry Wolkowicz (Waterloo, Combinatorics & Optimization). The successful applicant will have completed (or be very near completion of) a PhD in Operations Research, Electrical Engineering, Computer Science, or a related field. Preference will be given to candidates with documented expertise in mathematical programming techniques. The starting date will be determined by mutual agreement. The initial contract will be for 6 to 12 months, with a possibility of extensions up to a maximum of 2 years in total. Applicants should send a CV and list of referees to Professor Miguel Anjos ([log in to unmask]) as a PDF (preferred) or Word file. Applications will be accepted until all positions are filled.
