He has participated in a wide variety of research studies devoted to advancing diagnostic and therapeutic techniques and technologies for head and neck cancer such as fluorescent imaging, biosensing, photodynamic therapy, multimodal therapies, and oral cancer surgical reconstruction techniques.

He serves as a reviewer for multiple peer-reviewed journals, including Nature Biomedical Engineering, Head and Neck, Laryngoscope, Experimental Biology and Medicine, International Journal of Otolaryngology, Otolaryngology-Head and Neck Surgery, and is an editor for the Annals of Surgical Oncology.

Among numerous recognitions, honors, and awards, Dr. Sumer has been recognized as among the best otolaryngology physicians in North Texas by D Magazine, is the recipient of a Texas Instruments Corporate Award for Research, the Triological Society Francis Lederer Award,  the FUSION Grant for Nanotechnology Research, and the SEBM Best Paper Award in the Alan MacDiarmid Interdisciplinary Research Society for Experimental Biology and Medicine. He serves as principal investigator on several research projects funded by R01 awards from the National Institutes of Health (NIH) and the National Cancer Institute (NCI), and grants from the Cancer Prevention and Research Institute of Texas (CPRIT), and biotechnology companies such as OncoNano Medicine. He is also co-PI on the UT Southwestern Immuno-Oncology Translational Network (IOTN) i3 Center as part of the Cancer Moonshot from the National Cancer Institute.
