Brief Bio
I have completed my Master’s Degree in University of Fribourg in 2022 with my Master Thesis “Comparing the Impact of Data Imputation on Time Series Downstream Tasks”. Since May 2022 I am a PhD candidate at eXascale Infolab, supervised by Mourad Khayati and Philippe Cudré-Mauroux.
I have been working with eXascale Infolab on time-series related work since my Bachelor in Computer Science (with Mathematics as a minor) when I did my Bachelor Thesis under the supervision of Mourad Khayati, after which I have worked at eXascale Infolab as a programmer for two years. My current research focus is matrix decompositions, time series analysis and data cleaning.
