Welcome to the Presentation on Presentation IMMERSE 2020 4 -29 -20 Presenter: Aaron Hawkins Questions: Curated in Chat

Outline • Technical presentations versus other • Using Power. Point Slides • Backgrounds, colors, fonts, sizes • Organization • Too much/too little information • Content • Enough background information for your audience • Avoid equations and gory details • Emphasize big picture and conclusions

Outline (Cont. ) • Presenting (Now with Zoom!) • Try to be natural – use the camera • More slides than when in person • Don’t read slides • Don’t over/under prepare • Don’t over/under explain • Don’t go crazy with the pointer • Handling questions

Technical Presentation versus Other Presentations Technical Presentation – You do all the talking until someone asks a question – Delivering scientific results Church Presentation – Usually do a fraction of talking – Include stories, feelings, personal experiences

Technical Presentation versus Other Presentations (continued) Technical Presentation – Can have “personality” but should maintain a degree of professionalism – Power. Point Church Presentation – More personable – You ask the questions

Power. Point Presentation Guidelines Background Can’t Go Wrong Plain White Avoid Distracting backgrounds Fonts Ariel Anything distracting

Power. Point Presentation Guidelines Text Size Can’t Go Wrong Avoid Bigger than 18 point Smaller than 18 point (16 point) (14 point) (12 point) Colors Lots of contrast between text and background Little contrast between text and background or distracting

Power. Point Presentation Guidelines Can’t Go Wrong Avoid Background Plain White Distracting backgrounds Fonts Ariel Anything distracting Text Size Bigger than 18 point Smaller than 18 point (14 point) (12 point) Colors Lots of contrast between text and Little contrast between text and background - background or distracting

Power. Point Organization • Title Page • Outline – can be substituted for introduction slides • Body • Summary slide outlining conclusions

What to include on a Power. Point Slide Include Graphs Diagrams/Pictures Important Equations Key measurements Conclusions Avoid Long Derivations Computer Code Lists of measurements

Two Pump Phase Matching Double Pump Configuration Single Pump Configuration Input signal fp ( f 0 ) (Pump 1) Limited tunability Converted signal Can be tuned throughout Input the whole bandwidth Limited Tunability Pump signal fin Dummy signal fc f 0 ( 0) f 1 f 2 frequency fs_d D f 1 = f 2 0: center wavelength fc = 2*fp-fin Converted signal Can be tuned throughout the whole bandwidth Dummy Pump fin fp 1 fs 1 f 0 ( 0) fp_d fc fp 2 fs 2 fp 1 = fp 2 fs 1 = fs 2 fc = fin + fp_d - fs_d • Middle of the two pumps (input signal and dummy pump) needs to be ~ 0 We tune dummy pump wavelength to get input wavelength tunability • Middle of the dummy signal and the converted signal needs to be close to 0 We tune dummy signal wavelength to get input wavelength tunability • tunability is limited by EDFA (~ 25 nm) Y.

Videos and Animation • Can be extremely effective • Embed and make sure it’s bulletproof • Don’t leave video looping

Technical Content Background – Adjust to your audience – What do you need to know to understand significance of what I’m talking about – Why should you care – Why what I’m doing is so great Background slides could range from 1 to most of the talk depending on your audience

Technical Content Mental state of most audience members: sleepy, lethargic, bored, distracted, defensive, hungry, digesting Things people like • Big pictures • Summary Things people don’t like • Thinking too hard • Gory details

Technical Content Mental state of most audience members: sleepy, lethargic, bored, distracted, defensive Things people like • Results • New Stuff • Graphs with Labels Things people don’t like • Repetition • Endless equations • Raw Code • Endless talking

Number of Slides • For In-Person Presentation 1 to 2 minutes per slide • For Webinar or Zoom Presentation 30 to 40 seconds per slide • For your 12 minute presentations 18 to 24 slides

Stay on Time! • Two 15 minute Technical Presentations in 30 minutes – 12 minute presentation – 3 minute Q&A • Session Chair Will Cut You Off After 12 minutes

The Act of Presenting • Try to look and sound natural • Don’t read slides • Don’t over/under prepare • Don’t over/under explain (stall out) • Don’t go crazy with the pointer

Acting Natural, Lots of Eye Contact Example

Integrating Microfluidics and Hollow Waveguides 4) End Coupling of Solid and Hollow Core Waveguides 5) Integration of Macroscopic Fluid Reservoirs 1) Hollow Core Waveguides 3) Intersection of Solid and Hollow Core Waveguides 2) Bends and Intersections of Fluid Channels

Don’t Read Slides Example

SIM – Key to the Operation § Electrons created during ionization are collected at N+ region. § Holes created during ionization are directed towards the P+ substrate instead of back towards the current source → avoid carrier recombination and gain suppression Fig. 4 Different carrier transportation routes within the device

Over/Under Prepare Example

Anti-Resonant Reflecting Optical Waveguides 1) Hollow Core Waveguides n 3 n 2 d 0 kx k core, n 1 kz n 2 n 3 Substrate • First proposed by Dugay et al. (1986) • High-index cladding: antiresonant Fabry. Perot cavity in transverse direction • Low-loss propagation in z-direction • Single mode • Additional layers reduce loss

Over/Under Explain Example

SU-8 sacrificial core • Rectangular core defined by photolithography • Core removal: H 2 SO 4 + H 2 O 2 Waveguide width < 10 Top layer thickness

Going Crazy with a Pointer Example

SU-8 sacrificial core • Rectangular core defined by photolithography • Core removal: H 2 SO 4 + H 2 O 2 Waveguide width < 10 Top layer thickness

Some Zoom Specific Guidelines Use the Camera!

Some Zoom Specific Guidelines Look as Professional as Possible Camera at face height ! w o L o To Just Right

Some Zoom Specific Guidelines Look as Professional as Possible Professional Looking Background Save for F&F Clean and Simple

Some Zoom Specific Guidelines Look as Professional as Possible Don’t Backlight So You Are Only A Silhouette Too Mysterious Friendly Human

Some Zoom Specific Guidelines How to Handle Questions State Your Strategy Up Front Large Group >20 Smaller Group <20 Ask someone to collect and curate questions as you go. Answer at the end. Have people “raise hand” or start speaking. Answer at the end.

Some Zoom Specific Guidelines Check your Tech Microphone Platform Computer mic versus external mic How’s your network connection? Background noise? Do you understand screen sharing?

Conclusions • Being well spoken in technical presentations extremely important • How strangers see you • Practice, practice. . . • Watch other people and decide what you like, what you don’t • Let’s learn from each other. . .

Things to Look for in Critiques • • • Clean and clear slides Good pace and timing Engaging during presentation Use of audio and video Did I learn anything?
