Until that last gasp of earthly air lights up the chandelier of my Lungs...Before that last rush of blood shakes the chambers of my Heart...        i will be seeking you, not in the confined realm of physical reality, but  in the infinite realm of my dreams and the black holes of my imagination...

I would never search for perfection for I find so much beauty in the individuality and humanity of flaws and perceived imperfections, also known as character and uniqueness to the more optimistic types....

Ischemia of Esophageal Wall – a Mechanism of Esophageal Pain
Goal of this study is to determine if ischemia of esophageal wall is the cause of esophageal pain. These studies will be conducted in healthy normal subjects and patients with esophageal pain using laser Doppler perfusion technique to determine the temporal correlation between symptoms and esophageal wall blood ischemia. Furthermore, we will determine if longitudinal muscle contraction of the esophageal wall causes reduction in esophageal wall blood flow. We will also explore the temporal correlation between esophageal symptoms and longitudinal muscle contraction of the esophagus using ambulatory high resolution manometry

2008-2011, Engineering and Physical Sciences Research Council (EPSRC), Grant EP/E029868/1, UK

Research grant for investigating “A Novel Analogue Bio-impedance System-on-a-chip for Monitoring of Neonate Lung Function”.
Role: co-PI
The goal was to develop the component parts for a vitally needed integrated bio-imaging system for use to monitor lung function of neonates and children in ITUs. This novel system is based on the application of Electrical impedance Tomography (EIT) as an imaging modality, which remains the only viable solution for this application. Throughout the lifetime of the project considerable interest in the use of EIT for lung imaging has grown amongst clinicians, and members of this group have contributed to an international collaboration to standardize on a developmental algorithm for lung imaging. One of the papers produced from this research achieved the Martin Black award for best paper 2009 from the Institute for Physics Engineering and Medicine (IPEM).

2007-2008, The Heart Centre Ltd., Athens Euroclinic, Greece

Role: co-PI
Research grant for producing “A new Software for the 3D reconstruction of Coronary Vessel Lumen from Monoplane Angiogram Images”.
The goal was to develop state-of-the-art software in Matlab/C++ for the 3D Reconstruction of Coronary vessels from 2D Angiogram images. Two such software were developed in the latter project.

Professional Development

Course Modules:


Designed the ‘Pattern Recognition’ Course Module (i.e., Slides, Booklet, Lab Assignments, Homework) for the graduate program at City University, London. It was designed in such a way to help students gain pattern recognition skills essentials in order to identify, understand, analyze and interpret images, along with the practical experience of trying out pattern recognition techniques in a MATLAB environment.


Designed the ‘Soft-Field Imaging Course Module (i.e., Slides, Booklet, Lab Assignments, Homework) for the graduate program at City University, London. The module provides a solid foundation to understand the technical content, and open problems of Soft-field Imaging, Methods to provide and to prepare a student for research and development in various aspects of Soft-field imaging. The module provides an up-to-date review of the history of the development of soft-field imaging techniques, the present state of knowledge, and an overview of future developments and applications.
