About me

I am a postdoc researcher at Karolinska Institutet focusing on the incidence and prognosis of cancer, and comorbidities between cancer and other chronic diseases. 

Research description

My previous work was focused on: 

1. Psychosocial risk factors and cancer incidence

Specifically, I have studied psychological distress as a risk factor for the incidence of breast cancer during my thesis work, and whether anti-inflammatory medications could play a role in the prevention of breast cancer.

2. Prognostic factors of cancer

For example, I have studied the prognostic role of endocrine treatment, circulating vitamin D and neuroendocrine gene mutations in breast cancer, and inflammation-based prognostic score in lung cancer. I have also been involved in building prognostic models for breast cancer using machine learning.

3. Mental health in cancer patients and their families

I have studied the increased risk of mental disorders among patients with cancer and their spouses, and whether anti-inflammatory and anti-microbial medications could counteract the increased risk.
