During that time he worked on a number of projects including Nimrod ground replay systems and early thermal imaging devices.
His first degree is in Mechanical Engineering from Brunel University with Biomedical Engineering Specialsm in the final year. He gained a masters from Imperial College in Computing and his PhD from Middlesex.
He is a Chartered Engineer with the Institution of Engineering Designers.
Teaching and Learning interests include Engineering simulation and modelling, Computer-Aided Engineering, Research methods and statistics, Biomedical / Clinical Engineering.
Dr Tizzard is currently leading the BEng in Biomedical Engineering degree programme that has been running since 2014.
He is author of An Introduction to Computer-Aided Engineering published by McGraw-Hill in 1994.
Research interests include: Electrical Impedance Tomography, Deep Brain Stimulation, Computer-Aided Design, geometric modelling (including finite element modelling) and biomodelling. Doctoral students welcome in all related areas. Dr Tizzard has over 60 publications in conference proceedings and Journals.

Dr Tizzard has been jointly responsible for acquiring and managing around £1.2M of research funding. Recent grants include:
A Novel Analogue Bio-Impedance System-On-A-Chip for Monitoring of Neonate Lung Function.
EPSRC EP/E031633. 2007. Co-investigator. £182k. Development of a non-invasive and safe imaging system to provide continuous monitoring of lung gestation in preterm neonates using Electrical Impedance Tomography (EIT). The project was carried out in conjunction with University College London (UCL), City University and Great Ormond Street Hospital.
New imaging methods for the detection of cancer biomarkers.
EPSRC EP/G061572/1. 2009. Co-investigator. £944k Exploration of the use of gold nano-particles for the detection and treatment of colorectal cancer. The gold nano-particles were investigated as a possible contrast agent for EIT and a possible transport mechanism for cytotoxic drug delivery or heating.
Develop of research collaboration for breast cancer screening using EIT
British Council Prime Minister's Initiative. 2010. Grant Holder. £1500 UK-US Travel Grant with Dartmouth College NH. To discuss further collaboration following a publication on improving the forward model for EIT of breast.
Continuous Regional Analysis Device for neonate Lung (CRADL).
Horizon 2020, grant agreement No 668259. 2016. Co-investigator. c €1 M. (Total €5.5 M). Each year 15 million babies are born prematurely and many suffer from respiratory failure due to immaturity of the lung and lack of control of breathing. Although respiratory support, especially mechanical ventilation, can improve their survival, it also causes severe injury to the vulnerable lung resulting in severe and chronic pulmonary morbidity lasting in to adulthood. In order to address this, CRADL investigated the use of Electrical Impedance Tomography (EIT) technology to establish a monitoring tool for interventions in the paediatric population.
Preterm Neonate / neonatal Embedded Universal Microelectronic wearable Acquisition For Cardio Respiratory Intensive Therapy (PNEUMACRIT)
EPSRC. EP/T001240/1. 2019. c £1 M. To create a cost-effective, agile, wearable multi-sensor system capable of providing continuous, non-invasive, radiation free, bedside information on regional lung aeration and ventilation during daily clinical care of (preterm) infants and children with respiratory failure.
