Specializations

Thoracic Oncology and Solid Tumors

Clinical research in medical oncology with a strong focus on non-small cell lung cancer, including HER2-mutated and EGFR-mutated disease, as well as broader advanced solid malignancies and head and neck squamous cell carcinoma.

  • Non-small cell lung cancer
  • Head and neck squamous cell carcinoma
  • Advanced non-clear cell renal cell carcinoma
  • Melanoma
  • Cancer cachexia

Research activity also extends to combination immunotherapy and treatment strategies for metastatic cancer and tumor-related weight loss.

Cardiovascular and Thrombotic Disease

Investigator involvement includes studies in atherosclerotic cardiovascular disease, heart failure, hypertension, hypercholesterolemia, atrial fibrillation, and prevention of major adverse cardiovascular events.

  • Heart failure
  • Atrial fibrillation
  • Acute myocardial infarction
  • Venous thromboembolism
  • Hypertriglyceridemia

Additional interest is seen in lipid-lowering therapy, thromboprophylaxis, and cardiovascular risk reduction in patients with established or high-risk disease.

Immune-Mediated and Inflammatory Disorders

Clinical work spans psoriasis, ulcerative colitis, rheumatoid arthritis, systemic lupus erythematosus, Sjögren's syndrome, and related autoimmune conditions.

  • Plaque psoriasis
  • Ulcerative colitis
  • Systemic lupus erythematosus
  • Rheumatoid arthritis
  • Sjögren's syndrome

Research also includes atopic dermatitis, alopecia areata, and other immune-mediated inflammatory diseases requiring targeted therapeutic approaches.

Hepatology, Respiratory, and Metabolic Conditions

Interest extends to chronic hepatitis B, chronic hepatitis D, hepatic encephalopathy, chronic obstructive pulmonary disease, non-cystic fibrosis bronchiectasis, and metabolic disorders linked to cardiovascular risk.

  • Chronic hepatitis B infection
  • Hepatic encephalopathy
  • Chronic obstructive pulmonary disease
  • Non-cystic fibrosis bronchiectasis
  • Hypertriglyceridemia

Work in this area also covers obesity-associated heart failure and lipoprotein(a)-related cardiovascular risk.

Ophthalmology and Hematologic Supportive Care

Additional clinical research includes retinal vein occlusion, geographic atrophy, open-angle glaucoma, and ocular hypertension, alongside supportive care in chemotherapy-induced thrombocytopenia and inherited bleeding disorders.

  • Geographic atrophy
  • Open-angle glaucoma
  • Ocular hypertension
  • Chemotherapy-induced thrombocytopenia
  • Hemophilia

These areas reflect involvement in therapies for vision-threatening disease and treatment-related blood count complications in oncology care.
