Trosolwyg
My research focuses on adult neural stem cells and adult neurogenesis. Neural stem cells in the adult mammalian brain have the capacity to generate new neurons, which are important for brain functions such as learning and memory, mood control, and body metabolism. I am interested in studying factors that regulate the stem cells and brain functions that are regulated by the stem cells and their cell progeny. I am particularly interested in determining how aberrant diet can influence the stem cells and how stem cells can regulate the food intake behaviour and development of obesity.
Interested in joining my research group?
I enjoy supervising students. Research in my group is suitable for undergraduate, Master's and PhD students. I am open to discussion about fellowship applications with postdoctoral candidates. If you are interested in joining the lab, please contact me by email.

Ymchwil
Rydym yn defnyddio ystod eang o dechnegau i astudio ffactorau genetig, epigenetig, fferyllolegol ac amgylcheddol sy'n rheoleiddio bôn-gelloedd niwral mewn ymennydd mamaliaid oedolion. Gan ddefnyddio imiwnocemeg, diwylliannau celloedd a delweddu treigl amser, rydym yn pennu potensial amlochrog a gwahaniaethu bôn-gelloedd a llinachau clonau celloedd unigol. Rydym yn astudio agweddau mecanistig ar reoleiddio bôn-gelloedd trwy ddelweddu calsiwm a chan yr electroffisioleg patch-clamp ar y cyd â'r dilyniannu RNA un gell. Ein nod yw chwilio am ffactorau newydd sy'n rheoleiddio bioleg bôn-gelloedd ac i ddeall sut mae bôn-gelloedd a'u hepil celloedd yn dylanwadu ar swyddogaethau'r ymennydd a'r corff.
Rheoleiddio bôn-gelloedd trwy ddeiet
Mae niwronau newydd yn cael eu cynhyrchu mewn ymennydd oedolion o fôn-gelloedd niwral mewn rhanbarthau arwahanol o'r enw cilfachau niwrogenig oedolion trwy broses o niwrogenesis oedolion. Mae dau gilfach niwrogenig sefydledig ac un heb ei hastudio'n ddigonol yn yr ymennydd mamalaidd. Mae cilfach niwrogenig yr hippocampws yn arwain at niwronau newydd sy'n hanfodol ar gyfer y cof datganol a rheoli hwyliau. Yn waliau'r ventricle ochrol, mae cilfach niwrogenig sy'n cynhyrchu niwronau anaeddfed, sy'n mudo i'r bwlb olfactory i gymryd rhan mewn swyddogaeth olfactory. Mae'r gilfach a archwiliwyd yn llai yn yr hypothalamws, yn waliau'r trydydd fentrigl ymennydd. Yma, mae celloedd arbenigol o'r enw tanycytes yn gwasanaethu mewn rôl ddeuol fel bôn-gelloedd putative yn ogystal â'r rheoleiddwyr metabolaidd i reoli'r ymddygiad bwydo, pwysau corff a heneiddio. Ein nod yw deall sut mae deiet yn dylanwadu ar allu tanycytes fel bôn-gelloedd niwral a nodi ffactorau genetig newydd sy'n ymateb i ddeiet mewn tanycytes. Y nod strategol yw darganfod genynnau penodol y gellir eu trin mewn tanycytes a'u hepil celloedd i frwydro yn erbyn datblygiad gordewdra a achosir gan ddeiet.
Cyfansoddion gwrth-ordewdra
Mae gennym ddiddordeb mewn pennu mechanims cellog a moleciwlaidd o weithredu cyfansoddion gwrth-ordewdra. Rydym yn ymchwilio i botensial niwrogenig cyfansoddion gwrth-ordewdra newydd a sefydlwyd yn flaenorol. Ein nod yw defnyddio niwrogenesis oedolion a niwronau newydd-anedig fel targed ffarmacolegol o therapïau gwrth-ordewdra cyn-glinigol.

Bywgraffiad
I am a senior lecturer of the Biomedicine Division within the School of Biosciences at Cardiff University. My original training lies in ion channel biophysics and physiology, however, over the last decade I have been studying the neural stem cells in the brain.
Between 2000-2003, I conducted my diploma Master’s thesis at the Institute of Experimental Medicine of the Academy of Sciences of Czech Republic in Prague, where I investigated the electrophysiological and morphological properties of reactive astrocytes in a model of mechanical brain injury. To deepen my understanding of ion channel biophysics, I enrolled as a PhD student at The University of Texas Health Science Center in San Antonio, USA. In the laboratory of Dr. Robert Brenner, I studied the effects of alternative splicing, reverse phosphorylation and accessory subunits on molecular kinetics of calcium activated (BK) channels and their role in action potential waveform and firing in the granule cell neurons in the hippocampus.
During my post-doctoral career, I have focused on adult neural stem cells and adult neurogenesis, the process of generating new neurons in the adult brain. In 2008, I have joined the laboratory of Professor Amelia Eisch at the University of Texas Southwestern in Dallas. I have led a research in small molecule screening to characterize one of the most used drugs to upregulate adult neurogenesis in the hippocampus called Isoxazole 9. Also, I have studied the effects of epigenetic (such as Brg1) and genetic (Mef2, Cdk5) factors on the biology of adult neural stem cells. In 2013, I relocated back to Europe as a Marie Curie Fellow of the European Research Council to the laboratory of Professor Magdalena Götz. At the Institute of Stem Cell Research of the Helmholtz Centrum Munich and at Ludwig Maximilian University of Munich, I completed the research arch of my career by showing that adult neural stem cells in the brain are mechano-sensitive thanks to the epithelial sodium channel. Also, I have collaborated on projects that involve so called direct cell reprogramming and new single-cell sequencing methods. In September 2019, I joined the Cardiff University as a senior lecturer. In my laboratory, I focus on the adult neural stem cells in hypothalamus and the role of metabolism and diet on their stemness and biology.
