Ehsan's work focusses on multiomic and high dimensional approaches to understanding the immune response to cancer in patients and mouse models. His recent work has focussed on:

1. Cancer antigen immunogenicity using a novel measure of difference-from-self [12].

2. The immune microenvironment of cancer, in particular in relationship to mechanisms of immune function [5, 9], dysfunction [2, 6, 10], the T cell receptor landscape [4] and cancer neoantigens as drivers of immune failure [1].

3. The anti-PD1 agent pembrolizumab as a cure for rare gestational tumours and mechanistic aspects of its action [13].

Ongoing work is focussed on:

1. Application of machine learning approaches to study immune activation using routinely collected patient data.

2. Combining high dimensional flow cytometry, single cell RNA and TCR sequencing to understand the phenomenon of partial tumour control.

3. Mechanisms of anti-PD1 activity and in particular the effect of dose frequency on T cell function.
