Heysem Kaya completed his PhD thesis on computational paralinguistics and multimodal affective computing at Computer Engineering Department, Bogaziçi University in 2015. He has published over 70 papers (1.5K citations, h-index=23) in international journals and conference proceedings. His works won six Computational Paralinguistics Challenge (ComParE) Awards at INTERSPEECH conferences between 2014 and 2020; as well as three ChaLearn Challenge Awards on video-based personality trait recognition (ICPR 2016) and explainable computer vision & job candidate screening (CVPR 2017) competitions. His team was the first runner up in video-based emotion recognition in the wild challenge (EmotiW 2015 at ICMI). His research interests include mixture model selection, speech processing, computational paralinguistics and affective computing. He serves in editorial board of SPIIRAS Proceedings, as well as reviewer in more than 20 journals including IEEE Trans. on {Affective Computing, Neural Networks and Learning Systems, Multimedia}, Image and Vision Computing, Computer Speech and Language, Neurocomputing, Speech Communication, Digital Signal Processing and IEEE Signal Processing Letters.
