My research interests include
Non/semi-parametric estimation,
Errors-in-variables problems,
Shape-constrained modeling and inferences,
Functional data analysis,
Statistical analysis of random objects.
New challenges in noisy data analysis and statistical modeling for complex data always appeal to me.
I am also highly interested in interdisciplinary collaboration, including an ongoing project with Dr. Ondrus (UIC Chemistry) and the interdisciplinary project with Dr. Stabryla (UIC Civil, Materials, and Environmental Engineering), Dr. Huang (UIC Mechanical and Industrial Engineering), and Dr. Ackerman (UIC Obstetrics and Gynecology).
