Plenary Speakers
Emmanuel Beaurepaire
École Polytechnique, FRANCE
Color and multicontrast multiphoton imaging of brain and scattering tissue
Multiphoton imaging is popular for tissue studies due to its capability to maintain subcellular resolution in scattering samples. It also enables multiparametric imaging when combining wavelengths, polarization and nonlinear responses. The talk will discuss advances in high-information content microscopy.
About the Speaker
Emmanuel Beaurepaire is a tissue multiphoton microscopy specialist. He works at the Laboratory for Optics and Biosciences (LOB) at École Polytechnique in Palaiseau, France, where he is a research director appointed by the CNRS. The LOB microscopy group has pioneered several multiphoton imaging developments, including multicolor and label-free nonlinear imaging, two-photon light-sheet excitation and wavefront control. These developments aim to address issues of complexity, speed and depth in tissue imaging. We apply these strategies to study embryonic and nervous tissue development and to develop optical diagnostics.

Bridging Engineering and Critical-Care for Optical Neuromonitoring (BEACON)
Saturday, 25 April 09:00 - 16:00
This full-day consortium brings together clinicians and engineers to discuss state-of-the-art optical neuromonitoring technologies for extracorporeal membrane oxygenation (ECMO) patients.
The main three goals are:
(1) Bring together clinicians and engineers for direct conversation about challenges and opportunities for optical neuromonitoring in ECMO care.
(2) Document current strengths, gaps and opportunities through structured SWOT analysis for group dissemination.
(3) Establish connections for new collaborations and fundable projects. To achieve this, the meeting will feature clinical and engineering keynote addresses, two 90-minute topic-focused sessions, each with 4-6 short (10m) panelist talks followed by a 30m panel discussion.
The event will conclude with an interactive SWOT analysis to summarize discussion, document key challenges and opportunities and establish next steps for this new working group. Optica Members Only. RSVP Required. Please RSVP here.

Panel Session I: Is Helping Patients Enough? What Makes for a Successful Product
Tuesday, 28 April 17:00 - 18:30
Las Ojas I,II,V,VI
Researchers want their technology to be used by patients around the world, fulfilling an underlying driver for their work. A possible path to realize this goal involves commercialization of this technology via a major player in the market that can handle final development and distribution. This session will discuss what makes a particular technology attractive to a company. How is the unmet need being solved to address a market, with considerations, for example, of assessing fit into existing workflows, cost margins and general risk reduction.
Two invited speakers from large medical device companies will weigh in on what they look for during discovery - both internal and via acquisition. The presentations will be followed by a Q&A opportunity with additional panelists.
The panel will be followed by a networking reception to provide an opportunity to continue important conversations and network with industry representatives.

The Industry Chairs are organizing an engagement event to provide an opportunity to continue important conversations and network with industry representatives. Details will be provided soon.
Panel Session II: Building an Effective Start-up
Wednesday, 29 April 10:30 - 12:00
Las Ojas I,II,V,VI
Start-up companies fill a gap between early stage research and de-risked technology or a completed product. Founders must consider how to structure product development to achieve their goals in the time frame of the funding runway. Critical to this is defining the end game at the beginning - what does success look like to you as a founder? How are milestones and funding rounds planned to maximize likelihood of this success?
Two invited speakers will share their experiences. The presentations will be followed by a Q&A opportunity with additional panelists.
