About Me
I grew up in the eastside of The Netherlands, more specifically, in a small town called Duiven. As a child I was inquisitive and liked my little chemistry box including simple experimental tools as pH strips. The curiosity of science brought me to the HAN University of Applied Sciences in Nijmegen, where I started the chemistry program in 2010. I figured out quickly that analytical chemistry was my ambition, this led to a research internship of 5 months at RIKILT, an institute of the Wageningen University and Research center, where I worked for Dr. Stolker. My research included method development of veterinary drugs in plants and soil using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). I developed a strong interest in mass spectrometry, and associated sample preparation methodologies at RIKILT. Closer to the end of my Bachelor program I decided to join the Food & Pharma track, which is a combination of classes and research at the HU University of Applied Sciences in Utrecht. Under supervision of Dr. Chamorro-Perez was my research focused on phytochemical analyses using LC-MS. Whereafter I fulfilled my Bachelor’s degree overseas, to work on my graduation research under the direction of Dr. Yost at the University of Florida. This project included simulated breath analysis on several biomarkers related to the liver disease cirrhosis. I utilized multiple ionization sources combined with MS and high-field asymmetric waveform ion mobility spectrometry (FAIMS). Shortly after graduation I joined the Yost research group as a graduate student (spring 2015).
Research Interests
I am interested in a wide range of applications using mass spectrometry and the fundamentals behind these methodologies. Some examples of fields where I am currently working on are development of fast separation of complex mixtures, such as isomers, using ion mobility spectrometry (IMS). I am exploring the use of classical drift tube IMS and differential IMS, both in combination with mass spectrometry (MS). Furthermore, chromatographical separation associated with sample preparation for the reduction of matrix effects and improving the separation efficiency, gets my attention to assist other developed methods and bring it to the next level. Environmental and food sciences has always motivated me to work on, the fields are important in our daily life and develop in a high speed. These challenges need well developed scientific approaches to reach estimated results. Another interest where I am currently working on is clinical based, focusing on biomarker discovery and assay development. The clinical relevance of certain methods is very important in these strategies to make it applicable for the field. Close collaboration between our research group and the medical school of the University of Florida provides plenty possibilities of MS research in the clinical field. Metabolomics is a growing field of research, which results in issues in reproducibility. I have developed a method using isotopic ratio outlier analysis (IROA) in combination with ion mobility to increase reproducibility and certainty in compound identification. Environmental and food sciences have always motivated me to work on, these fields are important in our daily life and are developing in a high speed. Associated challenges need well developed scientific approaches to reach results faster and reliable.
