Hannah Batchelor is a Senior Lecturer in Pharmaceutics, Formulation and Drug Delivery. Her previous experience within pharmaceutical industry and the NHS brings extensive knowledge of drug delivery and the design of clinical trials. Hannah is passionate about involving children and young people in research and undertakes a lot of public engagement activity. 

Her research focuses on the design and manipulation of medicines to create age appropriate drug formulations to maximise clinical efficacy in paediatric patients.

She is an expert in optimisation of drug formulations to maximise their biopharmaceutical performance.


  • Professional Certificate in Learning and Teaching in Higher Education (2003)
  • PhD in Dug Delivery, University of London (2000)
  • BSc in Pharmacology and Chemistry, University of Sheffield (1996)


Hannah Batchelor graduated from a combined honours degree in Pharmacology and Chemistry at the University of Sheffield in 1996. She went on to work as a formulation scientist at Reckitt and Colman (now Reckitt Benckiser) primarily working on over the counter (OTC) medicines (Gaviscon® and Gaviscon Advance®).

In 2000 she was awarded her PhD in Drug Delivery from the University of London for a research project that explored the use of alginates in coating and protecting the oesophagus from gastric reflux.

She took up a lectureship in Pharmaceutics at Aston University immediately following her PhD where her research efforts focussed on targeted drug delivery systems and gastro-retentive therapies.

In 2008 she joined AstraZeneca as a senior scientist in biopharmaceutics where she worked on several drugs in development and lead the paediatric biopharmaceutics research group.

In 2011 she joined the R&D team at Heart of England NHS Foundation Trust as a Research Portfolio Manager to facilitate NHS lead researchers as well as develop collaborations with regional Universities.


Hannah Batchelor holds a postgraduate Certificate in Learning and Teaching and has experience in lecturing to undergraduate and postgraduate students. She has also published educational research papers.

She currently teaches on the MSc Pharmaceutical Enterprise; MPharm, MBCHB, Chemical engineering (MEng) programmes at the University of Birmingham.

Outside of the University of Birmingham she teaches on the MSc in Paediatric Medicines Development and Evaluation awarded by the University of Rome Tor Vergata (Global Research in Paediatrics (http://www.grip-network.org/index.php/cms/en/master_paediatric_medicines)).

She has also taught on a MOOC (Massive open online course) on “Drug Origins” (http://www.birmingham.ac.uk/postgraduate/courses/moocs/gbbb-drug-origins.aspx) which attracted 5500 participants in 2014.

She was responsible for writing a module within the SCRIPT project on paediatric prescribing (www.safeprescriber.org).

Postgraduate supervision

Hannah Batchelor is interested in supervising research projects in the following areas:

  • The use of scientific principles to design or manipulate medicines for paediatric use
  • Generation of understanding of paediatric physiology and biopharmaceutics to ensure clinical efficacy is maximised
  • Development of in silico tools to predict drug performance in paediatric populations 

If you are interesting in studying any of these subject areas please contact Hannah on the contact details above, or for any general doctoral research enquiries, please email: dr@contacts.bham.ac.uk  or call +44 (0)121 414 5005.

For a full list of available Doctoral Research opportunities, please visit our Doctoral Research programme listings


The main research themes are:

  • Scientific understanding of the impact of manipulation of existing medicines for use in children
    • Including understanding and implications of manipulations of medicines with food and/or drink
    • Data driven stability/shelf-life of manipulated medicines
  • Generation of understanding of paediatric biopharmaceutics to best design medicines for children
    • Including in vivo relevant dissolution testing
    • In vivo relevant drug release/diffusion from formulations and manipulated medicines
  • Demonstrate the value of in silico modelling to predict the performance of medicines in children to minimise testing in patients where possible
    • Including a review of PK and bridging studies in paediatric populations
  • Evaluation of the barriers to administration of paediatric medicines 

Ongoing research projects include FormPIC: formulation preferences in children and TabPIC: Tablet size, shape and colour preferences in children. 

She is currently co-supervising a PhD project; Konstantinos Stamatopoulos on, “In-vivo fluid mechanical models of drug delivery to the colon and in-vitro testing methods”. With Prof Mark Simmons, School of Chemical Engineering, University of Birmingham. 

She is also involved in an Innovate UK funded project, “Accelerating paediatric formulation development through smart design and predictive science“ with collaborators from AstraZeneca, Pfizer, Bristol Myers Squibb and GSK.

Other activities

Hannah Batchelor is a member the Clinical Research Network: Children, funded by the National Institute for Health Research, which is dedicated to supporting research into many different aspects of health care. 

Hannah gave a TEDx talk in April 2015 

Hannah is also the paediatric biopharmaceutics workstream leader within the European Paediatric Formulation Initiative (www.eupfi.org). 

Outreach activities to talk to children and young people about medicines and clinical research are an important aspect of Hannah’s work. She has visited schools, hospitals and community events.

See her personal website for further details 

Hannah has been invited to present at several National and International meetings on paediatric medicines development 

An online webinar is available from the  Global Research in Paediatrics (GRiP) series of "Meet the Expert in Paediatric Formulations".  This session "In-vitro biopharmaceutic methods in the development of oral dosage forms for children" 3rd October 2013
