Sandra Starke is a Research Fellow in Visual Analytics and Decision Making. She is working on the EU-funded cross-institutional project SPEEDD, which targets event prediction from both a machine learning and human perspective. Sandra is part of a team with Chris Baber, Andrew Howes, Neil Cooke, Xiuli Chen and Natan Morar, which is looking at human behaviour to understand how people integrate information from multiple sources to make decisions and predictions. This is largely based on sequential visual information sampling, and the majority of her work involves eye tracking.

Sandra’s interests cover the reliability of visually-guided decision making, decision making under uncertainty and perceptual learning. Having a background in Biomechanics research she also remains active in this field. Sandra holds a BSc in Biomimetics, MSc in Biomechanics and PhD at the interface of human visual judgement, expertise and biomechanics.

Biography

Sandra comes from an interdisciplinary science background, first studying at the interface of engineering and life sciences (BSc in Biomimetics, MSc in Biomechanics) followed by work at the interface of human visual judgement, expertise and biomechanics (PhD). She gained her PhD in December 2013 with the thesis "From sensors to senses: biomechanics and visual perception of movement in sound and lame horses", focussing on the biomechanics of sound and pathological equine gait and visual perception and judgement when detecting movement asymmetry. After a short research assistant position, she became project leader on a 6-month e-learning project in which she developed a 3D animation-based intelligent lameness teaching computer application with Stephen May and Gregory Miles. The result can be found at www.lamenesstrainer.com.

Having become deeply fascinated with vision and cognitive psychology during her PhD, she then decided to continue working on visual perception and decision making, which brought her to the University of Birmingham. Sandra ultimately fell for cognitive psychology and its related disciplines because the questions one can ask are almost too big to comprehend and so powerful that they won’t let you go. Those things that one might wonder about during a quiet night and where reading 50 books only gets you started. Where a lifetime of work only gets you a few steps closer. Where the everyday is the lab. She hopes that one day someone in this field might bring everything together and change the course of humanity for the better, through understanding of our own actions and enabling society to act on it. She is incredibly proud to be part of this journey, on whichever scale.

While the move from biomechanics to psychology may sound surprising, there are actually lots of parallels between the two disciplines: both disciplines try to drill down to the very fundamentals of action – in biomechanics looking for the principles that for example make a spider run and a tree self-heal, in psychology those principles that for example make us deny the reality of climate change or feel that we know enough to make a decision. Both disciplines develop models. Both disciplines need to understand the fundamental physiological underpinnings and constraints of the bodily ‘machine’. Both disciplines have a strong sense of adaptation, learning, evolutionary effects and variation. So – it all makes sense!

Research

Sandra is interested in how people turn the huge amount of visual information around them into some form of impression, belief or judgement, and in the reasons why and how this sometimes goes wrong. As part of the European Project SPEEDD, she is working on visual information sampling and information integration for two applied use cases: road traffic management and credit card fraud. At present this involves eye tracking and the development of efficient analysis protocols in Matlab including novel analysis approaches and metrics, development of interactive applications that integrate with eye tracking hardware, design of lab experiments and data collection ‘in the field’. This unites with her group’s work on Ergonomics, Decision Modeling, UI design and event recognition. For a list of publications coming out of this work, please check the ‘Publications’ section (currently several conference contributions accepted/presented and a paper under review).

At the side, Sandra is interested in perceptual learning, with experiments in the domain of movement feature recognition. At present this includes the investigation of different delivery methods on detection performance based on her animation-based learning tool ‘LamenessTrainer’. Remaining very interested in biomechanics, she is also currently working on motor control and biomechanics of tool use with Chris Baber and biomechanics of equine locomotion with Hilary Clayton. The outcomes of this work can also be found in the ‘Publications’ section.

During her PhD, Sandra worked on early recognition of ‘lameness’ in horses, a health complaint which manifests in a limping movement. Being able to decide on the content and direction of her PhD, she made the case for performing eye tracking studies, including a successful grant application to cover equipment costs. She hence combined biomechanics research to quantify movement adaptations of horses in various conditions as well as eye tracking research and perceptual studies to quantify what humans do to spot lameness, and what limitations the human eye meets. Her work in biomechanics included the development of Matlab routines for automatic processing and display of movement sensor data, which she then applied to clinical scenarios such as horse’s movement after flexion tests, on the circle or following diagnostic analgesia. Her work on perception covered visual scan patterns and decisions of students and experts when examining horses for lameness, detection thresholds for perceiving movement asymmetry in novices and experts, bias introduced by prior knowledge to the decision process of experts and novices and intuitive feature selection during movement assessment in novices.
