Research
Dr Seo investigates the pathogenesis of oral cancer, odontogenic lesions and immune-mediated oral diseases, with a particular focus on unfolded protein response (UPR) and endoplasmic reticulum (ER) stress. Techniques such as qRT2-PCR, IHC, histochemistry, western blot, cell culture and in vitro assays (viability, caspase-based, TUNEL) are employed in his research. He has an active research partnership with the University of Malaysia, Oral Cancer Research and Coordination Centre and the National University of Malaysia, as well as with Dunedin Public Hospital.
Dr Seo is also a reviewer for the Journal of Periodontal Research, Pathology and BMC Oral Health.
He received the Oral Presentation Award from the International Association of Oral Pathologists (IAOP), Elman Poole Fellowship, International Association for Dental Research-Colgate Postgraduate Award and Sir Thomas Hunter Scholarship, amongst others.
