I lead the Human Emotion Systems laboratory at Turku PET Centre and Department of Psychology, University of Turku. My main specialization is in human emotion science and medical imaging, but I am also interested in advanced statistical analysis of neuroimaging data. See my curriculum vitae, Google Scholar page and personal Finnish webpages for more details. I am also CEO for Nummenmaa Oy, please check out out our company website (in Finnish) too!
I joined the Turku PET centre in 2017 to investigate the role of different neurotransmitter systems in affective and cognitive processes using a large-scale neuroimaging database. My special interest is the neural and molecular basis of music-induced emotions. I obtained my PhD in psychology from the University of Helsinki and have expertise in different brain research methods including EEG, MEG and fMRI.
Senior staff and post-doctoral scientists
Kyoungjune “Arto” Pak
I am a nuclear physician and an assistant professor from Pusan National University Hospital, Korea. I joined the Emotion lab as a visiting scholar from August 2021. I am interested in brain-body interaction, which investigates how the brain controls the body, how the body controls the brain, and how they interact each other in physiological states as well as pathologic states. For more details, visit my Google scholar page, or my bibliography from PubMed.
Henry “Daddy-O” Karlsson
I am a senior researcher and adjunct professor, whose research interests lie in obesity, eating disorders, and other psychiatric disorders. I also work as a consultant psychiatrist and psychotherapist at Recuror and Turku University Hospital. More information can be found on my Google Scholar page.
I am a postdoctoral researcher with a particular interest in PET imaging methodology. My previous research has focused on brain PET neuroinflammation imaging with DTI, MRI and PET. At the human emotion systems lab, I am mainly involved in the implementation of modelling and analysis methods for PET neuroimaging data.
I am an associate professor from Fudan University working part-time at the PET Centre. My research is focused on the brain basis of psychopathy and violence, using fMRI to investigate the functional brain circuitry behind violent and non-violent psychopathy. I also use PET to elucidate their neuromolecular basis, including the endogenous mu-opioid and serotonin pathways. More information on my Google Scholar page.
Sanaz Nazani Farsani
I joined the Emotion lab to work as image processing specialist on the AIVO database. I focus on developing and implementing pattern analysis tehcniques to unravel imaging biomarkers for neurological conditions and classifying, and develop analytic techniques for quantifying brain-environment interactions in our large-scale imaging database.
I am working on a prospective study on the neural risk factors of developing obesity in the adolescence. We use positron emission tomography and focus on brain’s opioidergic and endocannabinoid systems in individuals with high versus low personal and familial risk for obesity.
I joined the Human Emotion Systems Laboratory in 2017 as a project researcher. The project focused on building and maintaining database, holding complex neuroimaging data, to the neuroscience community.
I am also interested to develop statistical and mathematical methods for analyzing imaging data from the big data perspective.
I study the brain basis of psychopathy and violence. Our studies will improve the understanding of the neural and psychological mechanisms of affective disorders, violence and impulsive behaviour. We use a multimodal neuroimaging approach with PET and fMRI.
I am a doctoral student in the University of Turku. I am also a clinical psychologist and an undergraduate student in Statistics. Data analysis is close to my heart. At the moment, I mainly work on PET data. My key targets of investigation are dopamine and the human reward system.
I am a doctoral student in the Social Brain project at Aalto university. The focus of my project concerns the neural mechanics of emotion transfer and the detection of emotional signals. We employ a multifaceted approach, combining behavioral measures, psychophysical experiments using fMRI and MEG, and naturalistic two-person fMRI to study these topics.
I am working on brain basis of human facial expression recognition using multivariate techniques.
My work pertains serotonergic and opioidergic circuits involved in positive and negative emotions. I am currently setting up behavioural, PET and fMRI paradigms for investigating the interplay of specific neurotransmitters in different emotional processes.
I am a medical doctor and work in the lab on data analysis procedures and computational tools for brain imaging database maintenance and development.
Before joining Human Emotion Systems Laboratory, I used to study group emotion by fNIRS. Now, I am a doctoral student here, studying attentional and affective mechanisms of empathy during naturalistic conditions and prosocial behavior by eye tracking and fMRI.
I joined the lab in 2020 as a research assistant in the eye movement project. I did my MSc in neuroscience and have previously been doing MEG imaging and studying neural mechanisms underlying depression. Currently I work on a fMRI and eye tracking project on the effects of bullying on the adolescent brain.
Research assistants and junior staff
I am a psychology student and work as a research assistant in the lab. I joined the Turku PET Centre in 2020. The project that I’m working with investigates individual differences in eye movements during cognitive and affective tasks. My work contains recruiting test subjects, collecting data and neuropsychological testing.
I lead the reptile reserarch division at the Emotion Lab and live in the Mordor basement. Currently I am feeding on frozen mice and gaining weight. In the summer I should be big enough to start my job as a research assistant scaring subjects in ultra-naturalistic PET and fMRI experiments on unconditioned fear.
My excited sound is responsible for keeping hundreds and hundreds of participants awake during fMRI scans. Every time I am delighted, they are asked to furiously press the response button to indicate they haven’t fallen asleep. You can hear hear a sample of my dark brown voice here.
Tiinuli “Päällikkö” Saanijoki
Tiinuli completed her infamous “HIT feels SH*T” thesis, and joined the Emotion Lab as a post-doc and travel quality assurance manager. She subsequently started working as the Research Director at the Turku PET Centre, making sure we all do only top-notch science at the centre.
After working as a post-doctoral fellow in PET data analytics and modelling, Marco moved to Karolinska Institutet for further developing his skills in PET imaging.
Lara worked with us on pattern recognition analysis of fMRI data. She ultimately decided that she wanted to do a career in business, and decided to try her wings in LA and London as web developer.
Enrico was our methods sorcerer and signal analysis prophet, playing a key role in many of our top fMRI and behavioural projects. We were unable to allure him to move permanently to Turku, and he decided to do a next post-doc at Aalto University.
The Snake Charmer Harri worked with us on the real fear project, managing subjects and our research assistant snake Jyrki. Harri decided to focus on his studies and wrapping up his master’s thesis, his work in Emotion lab surely makes him competent to deal patients with snake phobias!
Timo worked with us developing the Onni (“Bliss” in Finnish) stimulus rating tool, after which he returned to clinical training and is currently pursuing a PhD in cognitive psychology.
Actually being a part of Marco Bucci’s research group, Iina was adopted to the Emotion lab during the pandemic and remote work season. She bravely tackled the statistics and data management for the FDG database project done with Marco, and is now perfectly prepared for tackling her master’s degree in clinical psychology.
One of our super effective research assistants, Kia spent countless hours on data cleanup and management. She finally had to focus on her studies and theses, and we are definitely looking forward to meeting again in the lab.
Matias worked as a research assistant for us for some time, but decided to focus on his studies for a while. Maybe we’ll see him in the lab again some day?
Matt worked with us on unconditioned acute and sustained fear, and bravely figured out how subjects can be motivated to stay in the scanner for hours and hours. Training with us was worth the effort – he was offered a permanent Lecturer position at the Psychology at the National College of Ireland, Dublin.
