Jane Ladlow


University Senior Lecturer in Small Animal Surgery           

Jane is a Diplomate of the European College of Veterinary Surgeons (awarded in 2002). Jane’s main area of clinical research is brachycephalic obstructive airway syndrome, the objective assessment of airway function in these dogs and the development of effective surgical strategies for them. 

Jane moved to Animal Health Trust in September 2019 but is fully involved in BOAS research at Cambridge. 


David Sargan


Veterinary Geneticist & Senior Lecturer in Molecular Pathology

David is interested in comparative genetics of disease and in particular in genetic diseases of dogs. His current projects focus on a canine cone rod dysplasia, for which his group has very recently shown that the primary locus is subject both to genomic and translational modifiers, and mapped a modifying locus; on lens luxations in terrier breeds for which they have recently identified the causative mutation, and on breed predispositions to a variety of soft tissue sarcomas and a single type of carcinoma. In the last year he has also begun to work on projects on BOAS. David is also working on modelling the effects of CoI on prevalence of diseases with complex inheritance.



Nai-Chieh Liu


Clinical Research Fellow 

Nai-Chieh obtained her veterinary degree from the  National Taiwan University. She joined the Cambridge BOAS team as an MPhil + PhD student in 2011 working on developing a non-invasive respiratory function test for BOAS using whole-body barometric plethymgraphy and received training of upper airway surgery. She started her residency in small animal surgery in Feb 2018 and now moved onto her new position as a clinical research fellow running the BOAS lab. 

Nai-Chieh is particularly interested in head and neck surgery, respiratory physiology, and medical statistics. She is also an artist who enjoys painting portraits of her favorite study dogs and applying her skills onto medical illustrations. 



Francesca Tomlinson

Post Graduate Research Student

I qualified as a vet from the University of Cambridge in 2018 and went on to work in first opinion small animal practice in Bedfordshire. I returned to Cambridge in 2021 to study for a PhD under the supervision of Jane Ladlow with the BOAS research group. My work involves the investigation of the specific anatomical variations in brachycephalic dog breeds and the relationship with respiratory function and other breed-related health conditions. This work will aim to further our understanding of the risk of these conditions in certain breeds, help to improve the current health schemes, and also collect data for future genetic studies.


Lydia SmithLydia Smith RVN

Soft tissue specialist Veterinary Nurse

Lydia started her Veterinary Nursing career in 2011, training towards her qualification whilst working in a busy first opinion practice. During this time she developed a keen interest in patient welfare and management in a Veterinary setting. 

Once qualified, Lydia worked a short but very valuable stint at Queens Veterinary School Hospital as a theatre nurse. She learnt a lot about providing gold standard of care and the importance of excellent clinical standards. 

Lydia then went on to become Head Nurse at the practice she trained at for a further four years. This job role helped her invest more time into her passion – patient welfare. Over the four years she witnessed and learnt a lot about the problems commonly associated with BOAS patients, inspiring her to work closer with the breeds. Lydia is extremely excited to help with BOAS assessments as she believes this role could help promote better breed standards, with the long term aim to improve welfare standards overall for brachycephalic breeds.


PhilPhil Franklin MA VetMB MRCVS

Clinical Research Co-ordinator

Phil graduated from the University of Cambridge in 2010 after completing his veterinary degree, and received the Zoetis Prize for Small Animal Medicine that year. He spent two years in general practice, where he was awarded CVS New Graduate of the Year, before returning to The Queen’s Veterinary School Hospital as a Junior Clinical Training Scholar. Here he developed his interest in surgery and began research into BOAS, with a specific interest in clinical management of these patients. Phil now splits his time between working as part BOAS research group and in first opinion at a general practice in Thetford.


Dr Lajos Kalmar PhD

Post-doc Research Associate 

Zoologist mastered at the University of Veterinary Science Budapest (Hungary) in 2000, had his PhD from human genetics in 2007. Before he joined the team in the autumn of 2015 he worked in the Institute of Enzymology of the Hungarian Academy of Sciences, did research in the field of structural biology (especially in the field of disordered proteins). In the research team, he is responsible for the genetic studies related to BOAS and eating all the brownies that Nai-Chieh makes for Eileen.



Hattie Wright BSc MPhil

MPhil student in Veterinary Science

Hattie obtained a BSc in Zoology at the University of Reading, where she did her undergraduate research project looking at paedomorphosis and the evolution of the domestic dog. Wanting to continue with this theme whilst being able to apply research undertaken to improve canine health and welfare, Hattie was now working on her MPhil project here at Cambridge with the rest of the BOAS research team.




Eileen Troconis BSc MPhil

MPhil student in Veterinary Science

Before joining the BOAS research team, Eileen obtained an undergraduate degree in Biology at Amherst College. For her MPhil project she was investigating how the characteristic skull dimensions of canine brachycephalic breeds contribute to the development of the BOAS, and how they relate to the genetics underlying the condition. Next year, she hopes to pursue a degree in veterinary medicine.  In her spare time she enjoys talking to her family in Venezuela and the United States, as well as meeting new people and animals from all over the world.
