I am seeking motivated students interested in research in optimization and variational analysis. Prospective graduate students who wish to work under my supervision and have me serve as their thesis advisor are encouraged to contact me and apply through our graduate program (see the link). Undergraduate students at the University of North Dakota (UND) interested in research projects, theses, or independent studies are also welcome to reach out by email.
The M.S. programs in Mathematics and Statistics at UND offer graduate teaching assistantships that typically provide full funding for two academic years, including a nine-month stipend of approximately $18,000 and a full tuition waiver. International applicants must have an IELTS score of 6.5 or an equivalent qualification.
I am also recruiting UND graduate students for funded research assistant positions: two positions in Summer 2026 with a $6,000 stipend each, and one position in Fall 2026 with a $9,000 stipend.
Founded in 1883, UND is North Dakota’s flagship university and an R1 institution. Its M.S. programs prepare students for doctoral study or careers in academia, industry, and the public sector.
