About me

I have a background in Clinical Medicine and General Surgery, with expertise as a hepatobiliary surgeon in my country. In June 2018, I joined Professor Torkel B. Brismar Group as a PhD student and successfully defended my thesis in May 2022. Currently, I am working as a postdoctoral researcher within the same group, continuing my research pursuits.

Research fields

Liver cancer (hepatocellular carcinoma & cholangiocarcinoma), liver function/liver growth, radiomics/machine learning, body composition/sarcopenia, gadoxetic acid enhanced MRI

Research description

During my master's studies (2014-2017), I focused on a modified ALPPS procedure (radiofrequency ablation-assisted Associating Liver Partition and Portal vein ligation for Staged hepatectomy, RALPPS) for patients with hepatitis B-related hepatocellular carcinoma. ALPPS is an innovative technique known to stimulate accelerated liver growth in the future liver remnant, but it can also lead to increased morbidity and mortality. In this context, RALPPS was proposed as an alternative approach to classic ALPPS.

Liver function assessment plays a critical role not only in ALPPS but also in various other treatments. Accurate assessment of regional liver function holds immense clinical significance. Therefore, my doctoral project centered on utilizing gadoxetic acid-enhanced MRI to quantitatively evaluate liver function and predict postoperative liver failure, which is a fatal complication relating to liver function insufficiency. Additionally, I explored the integration of radiomics and machine learning techniques into liver function assessment and for the prediction of liver failure.

During my postdoctoral period, I have continued to delve into the aforementioned topics while also expanding my research field to include body composition analysis and its impact on liver growth, as well as liver cancer treatment outcomes. I have also been investigating cholangiocarcinoma and other liver cancer related areas.
