Vassili Karanassios

Vassili Karanassios' interests are in the area of micro- and nano-analysis (e.g., metrology), in micro- and nano-technology (e.g., micro- and nano-fluidics, nano-materials), and in development of miniaturized instruments that can be used on-site (i.e., in the field). Such instruments are typically fabricated on-chips so that they can fit in the palm of a hand or in a shirt pocket, thus allowing users to take "the lab to the sample". The sample may be a "patient" (for early diagnosis of disease) and the field may be a health clinic or the environment (e.g., the air we breathe or the water we drink). In addition, such instruments are being developed to have wireless-capabilities so that they can be included in the Internet of Things (IoT) and to have some smarts (via Artificial Intelligence, primarily using Artificial Neural Networks and Deep Learning approaches).
