Research Interest:  Osseointegration of Dental Implants / Surface modification / Bone graft Immunology of Periodontal Disease, Periodontal Disease and Systemic Conditions, Diabetes Mellitus and Periodontal Disease

Research Interest: Dr Mei's research expertise is in biofilms and biomaterials. His recent research activities are mainly focused on the mechanism and prevention of bacterial adhesion and biofilm formation on dental materials.

He has measured the adhesion forces between living bacteria and orthodontic materials using atomic force microscopy at a nano-level, and decoupled the bacterial adhesion forces into specific and non-specific forces. In addition, he has investigated measures for preventing biofilm formation using quaternary ammonium compounds. He developed a novel contact-killing surface by incorporating quaternary ammonium compounds into composite resin and studied its efficacy of killing the adhered bacteria and its bio-safety for human cells.

His other interests include randomized controlled trials (RCT) and evidence-based dentistry. He has investigated clinical methods for enhancing oral hygiene in patients wearing fixed orthodontic appliances.

Research Interest: Magnetic Resonance Imaging (MRI), image processing techniques, pattern recognition. Emphasis on reconstruction, analysis (e.g. segmentation, texture analysis, motion tracking) especially for the diagnosis and monitoring of brain tumors and neurological disease.

Research Interest:  Genomics, proteomics and inflammatory aspects of human breast cancer and chronic diseases.

Research Interest: His research has included enzyme catalase.

Research Interest: The focus of my research work is to examine the molecular mechanisms of autophagy, apoptosis, angiogenesis and metastasis, and develop novel drugs for the treatment and prevention of various cancers.

Research Interest: Molecular characterization of brain tumor stem cells  Therapy development for brain tumors Phase I/II Clinical Trial for malignant brain tumorsMolecular mechanism of therapy resistance of brain tumors Genetic mechanism for cell fate decisions in neural stem cells

Research Interest: Transplantation, transplant immunology, artificial organs.

Research Interest: Molecular Biology, Microbiology, recombinant DNA technology and biochemical methodologies.

Research Interest: As a professional with intensive interdisciplinary backgrounds, his research goals are to understand the human diseases mechanisms through studying the clinical relevant animal models, in the fields of Neuroscience, Oncology, Orthopedics, Molecular Immunology/Hematology, Pathology, Genomics/ Genetics and Stem cells.  Based on his research he has received several awards and honors, such as: Distinguished service award from University of Pennsylvania. He has authored more than 25 research articles, 2 books/chapters and 4 reviews

Research interest: Biomaterials, Drug delivery, Biomechanics of hypertensive cerebellar hemorrhage.

Research Interest: His research focuses on the studies of the lipid/cholesterol metabolic and signaling pathways in prostate cancer development and advanced progression; molecular targeting of prostate cancer; and oncogenic and tumor suppressive microRNA

Research Interest:  Currently Dr. Leiser is the head of the Laboratory for Oral Cancer Research and is supervising M.Sc. students in basic science research. Dr. Leiser specializes in surgical oncology and surgical dental rehabilitation in the maxillofacial region. The author of several scientific and clinical manuscripts in international peer-reviewed journals, he has actively participated as a lecturer in several international and national conferences in the basic sciences as well as at professional maxillofacial surgery and oncology conferences.
