Deputy Director of Graduate Studies in the School of Engineering
Natasha Khovanova studied for her doctorate in the Department of Physics at Saratov State University (Russia) and has a PhD degree in Physical and Mathematical Sciences. After her graduation and before moving to the UK, she held an academic post in the same department.
She joined the School of Engineering of the University of Warwick in 2010 and is a Reader in the Systems and Information Engineering stream and EPSRC Fellow.

Identification, stability and control of linear and nonlinear systems with application to diabetes
- Our primary aim is to understand physiological mechanisms of glucose absorption and describe the intra-/inter- subject variability of blood glucose variations in people with and without diabetes for early diagnosis and personalised management of the disease.
- Natasha is currently leading a five-year research project on early diagnosis and control of gestational diabetes as a Chief Investigator. It is a joint venture between the School of Engineering and University Hospitals Coventry and Warwickshire, funded by EPSRC UK, UHCW NHS Trust and Dexcom, and is supported by the Clinical Research Network of the National Institute for Health Research.
Time series analysis of complex signals and synchronisation phenomenon with application to cardio-respiratory coupling
- We study the underlying mechanisms governing the communication between the cardiovascular and respiratory systems with particular attention to the differences in athletes and non-athletes.
- Our main attention is the novel experimental design and application of the concept of instantaneous phase to detect cardio-respiratory entrainment at various respiratory rates and to utilise this non-invasive measure for tracking a person’s athletic development.
Development of machine learning and artificial intelligence methods with applications to limited data in clinical settings
- Our emphasis on the utility of machine learning for data-efficient classification, regression and survival analysis to overcome the common limitations inherent in routinely collected patient data, such as class imbalance, incomplete samples and limited data size, i.e.less than 10 observations per predictor variable.
Supervised and unsupervised machine learning and data-driven dynamic modelling with application to high-risk renal transplantation
- Our aim is to understand the role of donor-specific antibodies in HLA-incompatible kidney transplantation for risk stratification and effective treatment.
- This is a collaborative project between the School of Engineering, Leeds Teaching Hospital NHS Trust, NHS Blood and Transplant Birmingham and University Hospitals Coventry and Warwickshire NHS Trust
