Get to Know Me
What are the most interesting aspects of your work?
Every work of art carries emotion, history, and at times, a price that appears to defy any logic. I enjoy helping people understand why a banana taped to a wall can become a cultural and financial phenomenon. It is where passion meets reason, and that intersection never ceases to inspire me.
If you could have dinner with 3 artists from the past- who would they be?
Leonardo da Vinci, Andy Warhol, and Claude Monet - three artistic geniuses who saw the world differently and impacted it radically. I would probably ask Leonardo how he managed to mix science and poetry so effortlessly; Andy how he predicted our obsession with fame so accurately; and Claude how he captured silence in color.
Do you have a routine when visiting a museum/gallery?
Yes, I do. I like to start without a plan, to let intuition guide me before analysis takes over. I look for what stops me, what feels alive. I never follow the proposed path. Then, I circle back, read the labels, and connect the dots between emotion and context. I always end in the bookstore, of course - the only place where I still pretend impulse buying is research.
