First of all, let's get the age issue out of the way. I am 46, but I didn't want to be excluded by an age-based search. People tell me I'm well-preserved and look like I'm 38. You decide.
Another possible deal-breaker is that I have a 12-year-old son who lives with his mother. I spend an afternoon a week and roughly every other weekend with him. I'm open to having more children with the right person. Actually, I would like that, although if I end up with someone who adamantly doesn't want kids, I won't be crushed.
If you haven't been deterred, keep reading...

Originally from Paris, I've been in NYC for over 15 years now, and I love it, although I go back regularly to visit. These days, I meet more Americans in Paris than in New York!
I am very easygoing, not a snob like the stereotypical Frenchman. I could describe myself as warm, confident, honest, and fairly ambitious. I enjoy going out for a good meal, a play, a movie, live music - not much of a night clubber - but also staying home for a movie and some wine. I don't take myself too seriously, even though my work can involve life or death situations. I'm an anesthesiologist and critical care specialist, and I love my job, but when my workday is over, it's over!
My sense of humor can be quirky but playful. I'm a glass-half-full person and I always see the silver lining.

I've visited most of Europe, including Russia, the Ukraine and the Caucasus, Iceland, most of North America, Saudi Arabia and Dubai/Abu Dhabi, China and Singapore, Turkey, but I still have a lot of destinations of my wish list: next Argentina, India, Iran maybe?
In my opinion, one of the greatest ways to spend an evening is simply with good friends, having some wine and remaking the world.
I am not an athlete, but I keep in shape. Krav maga (a martial art developed by the Israeli military) is a great workout, plus you never know when it could come in handy. Watching sports, on the other hand, has never really interested me.
One thing that fascinates me is learning about other people and what makes them tick...

What I am looking for: someone who is smart, kind, caring, considerate, passionate, honest, adventurous, with a playful sense of humor. Chemistry is very important and cannot be figured out online or over the phone, so I am all for meeting early. At this point in my life, I am done with having short-term fun, and I'm looking for a long-term relationship.
The physical aspect is also a significant part of a relationship, and in that respect I am looking for someone who is not inhibited.
I am a great listener, and you can vent to me about your day; I won't offer solutions unless you ask me to.

I spend a fair amount of time working, with some research and teaching to keep it interesting and challenging.
The rest of the time, I try to have fun, and to be creative and productive, sometimes at the same time, sometimes not.

my job, but it challenges me enough to keep it interesting; languages; kissing; and quite a few other things for you to discover.

Depends who you ask. I would guess
My eyes
My smile
My accent (not a typical French accent; I keep people guessing)

- music: from opera (Wagner, Mozart) to blues and indie rock (by no means an expert though)
- movies: Happy-Go-Lucky, Pulp Fiction, Deconstructing Harry, Wild Strawberries, La femme d'à côté by Truffaut, Les enfants du paradis, Dhobi Ghat, La mala educación by Almodóvar, Conte de Noël by Desplechin, Carlos, Ma nuit chez Maud by Rohmer. The inn scene in "Inglourious Basterds" by Tarantino, and especially the immortal line "Say auf wiedersehen to your Nazi balls!"
- novels (I enjoyed A Visit From The Goon Squad, Super Sad True Love Story, Murakami, kind of grazing on Infinite Jest but moving slowly, currently reading 2666 by Roberto Bolaño ; The Master and Margarita is one of my favorites, even though I realize I probably don't get 9/10 of it; Nabokov and Philip Roth; Céline, Gide, Yourcenar) or non-fiction.
- Art (in small doses). My favorite painter is Egon Schiele. The Alexander McQueen show at the Met was amazing.
- Having been born and raised in France, I enjoy good food and wine, but I'm not a snob and I like BBQ with a beer or a bacon cheeseburger with fries from the local diner or BLT burger (not too often though) as well. I enjoy cooking when I have time, and I can make black rice with squid (with squid ink), the kind that I enjoyed in Barcelona, and mine is almost as good... I also make a mean tarte Tatin and a good cheesecake. Oh, and crêpes! Girls have dated me just for the crêpes...

Music.
Books, the paper kind; I don't have a Kindle but I read some books on the Kindle app on my phone or computer, easier to carry around.
Good wine and good food.
My Mac.
Love and sex.
Friends and family (some family members at least) but these are not things.

- my next project(s). I have a textbook coming out, now working on a novelized memoir, and trying to get funding for my research.
- my next vacation/trip.

I could be working, catching up with my sleep, out with friends, inside with a good book.

I sometimes annoy people involuntarily - although my filter is getting much better - like at this dinner where I said that the Sauvignon Blanc had a hint of cat pee.

you are looking for a serious relationship, but you don't take yourself too seriously.
